I think Aldridge has some legit resources in the team offices. The thing is, even if the team wants to do something, they may not be able to do something. It takes at least 2 teams to make a trade happen.
The other thing that I would throw out there is the possibility that Lamarcus might be the odd guy out. He still has a lot of value through out the league, but if you are going to move forward and not count on Greg Oden ever coming back, you need to get more physical up front. Lamarcus would probably be fine if teamed with Oden and the spacing worked out. But as is, the team lacks physical toughness and Lamarcus does not and will not ever bring that to the table. Meanwhile there are teams like New Jersey who are looking for somebody to open space for Brook Lopez who have been rumored to want to trade Favors, who is almost the exact opposite of Aldridge. He plays almost exclusively in the paint.
