Nice work Animart1! The Spanish press remind me a bit of the Japanese press with Ichiro getting much more exposure in his home country than from here. I think we all know Rudy’s capabilities and the apprehensive feelings around the league must be palpable.

Do they have barbecue in Spain?

I’ve added a lot of commas.

If you have a compound sentence of more than one complete clause, you should add a comma. Examples:
You wrote a very good post, but I decided to help you with the English. (both clauses have both a subject and a verb, so a comma is usually used. Sometimes it won’t be if the two clauses are very short, as in this case.)
I read your post and decided to help you with the English. (the second clause doesn’t have an explicit subject, the “I” is drawn from the first clause, so a comma is not usually used)
Tominhawaii once sent a message that he found in a bottle back to the sender. Tominhawaii once sent a message (that he found in a bottle) back to the sender. Tominhawaii once sent a message, that he found in a bottle, back to the sender. (clauses introduced by “that” or “which” are often not set off by a comma. This is not an additional thought, but a descriptive one. As such, it can be set off with commas, parentheses, or not at all. If the sentence is long, or there is danger of confusion between what is the descriptive clause and what is part of the main clause, it should be set off. Sometimes, in long sentences, where commas are used for other purposes, parentheses can be better. All three versions of that sentence which I’ve given are appropriate.)

Tominhawaii once sent a message that he found in a bottle back to the sender, but he found the bottle in Oregon and posted his response to her from Hawaii. (Here we have a combination of the principles. There are four clauses here. Tom sent a message is main clause #1. That he found in a bottle is a descriptive clause that does not need to be set off. The third clause is “He found the bottle in Oregon”, which is a complete clause, and so is set off from the first main clause by a comma. The fourth is “he posted his response”, but this one is not a complete clause because it shares the subject of the prior clause, so it needs no comma.)

So, anyway, after afflicting you with all that, maybe that will help you a little with your commas. I hope all of this helps a little, your English is definitely coming along nicely. Here’s my version, I’ve italicized the changes.

EL PAIS, probably the most important newspaper in Spain, published today this interview got by phone.

"I´m proud that some people compare me with Ginobili, because he is a great player. It is true that we look alike in some aspects of our game though Manu is Manu and Rudy is Rudy. Of course I would sign now to be the best sixth man of the League."

He understand English but need help when his teammates speak among them quicker.

 He understands English but needs help when his teammates speak more quickly among themselves. (“quicker” would work, but “more quickly” would be used more often in this context — I don’t really know why.)

"The work at the gym is nothing special but working on the court is different from the ACB. We start running very quick since the first day and playing all out."

"The work at the gym is nothing special, but working on the court is different from the ACB. We start running very quickly from the first day, and playing all out." (quick is an adjective, quickly an adverb. Rudy is quick, he runs quickly)

Asked about his first play in the court during his first training game he said “it was an alley-hoop after a pass by Sergio”, playing down importance.

Asked about his first play on the court during his first training game, he said, “It was an alley-oop after a pass from Sergio,” playing down its importance. (added several commas, moved comma after Sergio inside the quote)

He´s playing with Roy. “Is too soon to say what position I will play or how I am going to play. Sometimes Brandon plays PG and some times I do it too. But he is playing very well”.

He is playing with Roy. “It is too soon to say what position I will play, or how I am going to play. Sometimes Brandon plays PG, and some times I do it, too — but he is playing very well.” (added several commas, moved final period inside the quote. The final clause starting with “But” could have remained a separate sentence, but usually it’s best not to start a sentence with “but”.)

“I have not had yet a chat with McMillan on what he expects from me. He is hard (or harsh, I´m not sure about the English exact word) but there will no be problem with him. He is a great coach. Sometimes we joke on the Olympic final and on the traveling that the referees did not whistle to the Americans”.

“I have not had yet a chat with McMillan on what he expects from me. He is hard, (or harsh, I´m not sure about the English exact word) but there will no be problem with him. He is a great coach. Sometimes we joke about the Olympic final and about the traveling that the referees did not whistle on the Americans.” (hard would be tough or demanding, while harsh carries the connotation of being unkind. I would guess you want “hard” or “tough”, because even if Nate is “harsh” I doubt Rudy would be saying so publicly.

Rudy is optimistic, very confident of his quality as player and about what he can bring to the team. But at the same time he has a tremendous respect for the NBA and the requirements of his team. “By now, everything goes phenomenal. It is very important that I have Sergio’s support. Thanks to him I have adapted rapidly to the group and already we have done some barbecue with all the players, and all the trainers are helping me very much. I cannot complain”.

Rudy is optimistic, very confident of his quality as a player and about what he can bring to the team. But at the same time, he has a tremendous respect for the NBA and the requirements of his team. “For now, everything is going phenomenally (or "phenomenally well”). It is very important that I have Sergio’s support. Thanks to him, I have adapted rapidly to the group, and already we have done some barbecue with all the players — and all the trainers are helping me very much. I cannot complain." (phenomenal is an adjective, phenomenally is an adverb. Rudy is a phenomenal player who plays phenomenally. This adjective/adverb thing is a very common struggle for people learning English, and something I’ve noticed fairly often in your writing. Do you understand the difference between the two? I don’t know if Spanish has the same usage.)
 

Talking about playing time, Rudy says he thinks “always positive, never negative”. “Yes”, answers Rudy, " I know McMillan has spoken very well on me but by now he has not talked to me at all about the minutes that he thinks to give me. I hope I´ll be able to have minutes and help the team". The goal this year for the Blazers will be to get into the play offs.

Talking about playing time, Rudy says he thinks “always positive, never negative.” (another quote should almost always mean a new paragraph, even if one paragraph is very, very short)

“Yes”, answers Rudy, " I know McMillan has spoken very well of me but up till now he has not talked to me at all about the minutes that he intends to give me. I hope I´ll be able to have minutes and help the team." The goal this year for the Blazers will be to get into the playoffs. (playoffs is one word, not two)
 

" The team is young but there is a good prospect and we can take the challenge. We need a good start to achieve positive dynamics". For the present time they have not played any typical beginner’s joke on rookies but Rudy assumes that it will come. “I am not a rookie as usual because my teammates already know that I come from the professional basketball, but it will be funny and entertaining. I agreed that I am a rookie here”"

“The team is young but there are good prospects and we can take the challenge. We need a good start to achieve positive results (? not sure if this is the right word, but I don’t think dynamics is, either).” For the present time they have not played any typical beginner’s joke on rookies, but Rudy assumes that it will come. “I am not a rookie as usual, because my teammates already know that I come from a professional basketball background, but it will be funny and entertaining. I agreed that I am a rookie here.”

UPDATE: Similar interview at MundoDeportivo. New statements are:

They say that they interviewed Rudy by videoconference, organized by the NBA for the Spanish media.

Rudy will live in Lake Oswego’s residential zone, where also Sergio is installed.

This is all good, though we don’t usually install people in residential zones. Usually we install software on computers…. Perhaps “residential area, where Sergio is also living.”

" It is half a way between training court and Rose Garden. It is a central place, with shops, something important in order that my mother did not have to use very much the car".

" It is half-way between the training court and the Rose Garden. It is a central place, with shops, which is important in order that my mother does not have to use the car very much." (might also just say “so that my mother” rather than “in order that my mother”. The way you’ve done it is fine, but less common)

“Sergio is in an incredible moment, just now he is playing PG in the black unit (first team).”

“Sergio is in an incredible opportunity at this moment, because right now he is playing PG on the black unit (first team).”
 

He miss “his friends, his girlfriend (-twiggs, do something!-) and everyone who helped him”. The internet helps him to keep contact with Spanish basketball. His home page is ACB.com.

That’s awesome that they all got together to barbecue.

Get used to it, amigo. Just think, after a year in the NBA you can start taking an extra step and the refs will let you get away with it, too
