Presuming the team does not blow it up and start over the team is in need of a defensive minded center that they can pair with LMA. Greg (if he can ever get healthy) is th best option for this type of a player...even if his 75% of what he could have been. Greg brings the added advantage of a power offensive game, which further helps LMA as other teams have to account for greg (where as they can ignore guys like Pryzbilla).
Camby is great at the moment but even if they sign him to another contract, his contributions will be limited as he gets older. If the window is now then fine, but LMA has at least 6 or more years of championship type play.
Joel Freeland is a guy they have talked about bringing over. He has he size to play the 5, but he seems more like a 4. In either case he is a good all-around big who would be great as the third big off the bench, but not the defensive rebounder type that would really compliment LMA.
Besides Nate’s reluctance to play young guys, there really aren’t that many 5s available when the blazers are to draft that will have the impact needed to take this team to the next level...although there are some intreging talents (Mason Plumlee, Arnett Moultrie, etc.)
Greg should come cheap, and besides, they only dress 13 per game anyway. Greg’s potential (however distant it may be) is enough to warrant a roster spot...IMHO
