Jeff Clark has collected some pretty damning quotes. And in the comments are some more. There is a fine line between confident and cocky, it doesn't seem like his teammates and coaches outright hate him (anymore), and a trade is not on the table as per Kelly Dwyer. But obviously the Celtics are not completely happy with him either.
"Two seasons ago, before the banners and the plaudits and applause, when Rondo was in charge of a team that won just 24 games, he'd throw a no-look bullet and when it was dropped out of bounds he'd roll his eyes in exasperation. If he set up a shooter for the open jumper and it clanged off the rim, the shooter was subjected to the Rondo stare, a look steeped in disdain and aggravation. Rivers hauled his supposed floor leader into his office and asked him, 'Do you know your teammates hate playing with you?'"
"The single biggest thing with him," said Ainge, "is getting him to compete night in and night out."
"He’s stubborn," Ainge said. "He doesn’t always take direction well. He’s very bright and knows what he needs to do to be successful. "But sometimes he doesn’t understand what the team needs to be successful."
"I’m set in my ways," says Rondo, who believes his accuracy will improve with practice. "I don’t feel like I have to settle for a jump shot, because I can get to the basket at will."
On following instruction from Doc Rivers: "I’ve learned to handle it a little bit better," he says. "Even though I think I’m right."
Between this and his "dirty plays" e.g. in the series against Chicago fouling Miller and Hinrich, you have to wonder if his stock is as high as it once was - and if that attitude disqualifies him in the eyes of the Blazers front office if there ever was a chance for a trade.
