At least if you listen to the rumors. The first two descriptions are undeniable, but the third is still up for debate.
It all started with a Chad Ford comment during an ESPN chat session in June:
I think that the Blazers will listen to Aldridge offers. Seriously listen. Given how good he is, I do think there's a solid chance he's played his last game in a Blazers jersey. The Blazers aren't going to give him away obviously, but he's an intriguing trade target for a lot of teams.
Then the Daily Herald's Mike McGraw followed up with a report that Aldridge was unhappy in Portland: "Word is, Aldridge wants to escape from Portland's rebuilding project and has made it known that he'd like to land in Chicago."
Nothing has happened since then, but there's a lot of time left before the 2013-14 season begins. With rosters starting to get settled, the chances for a trade are higher than ever. Teams have identified their weaknesses and where they stand in the NBA hierarchy, so they're able to react accordingly.
For the sake of the argument, let's assume that the Blazers feel like they have to deal the big man. Which offers would force them to engage in discussions?
