Reality TV BS aside, they're actually two pretty interesting moves that the Sixers could make without giving up a ton and might help solve some of their size issues.
Humphries is an unrestricted free agent so he'd be a strict rental for the rest of the season (and is tradeable on March 1st).
Odom has a team option for next year at 8.2 million which I would assume the Sixers would probably decline unless he blew up so he could be a rental.
Humphries is averaging 13 and 10 and would be a good of the bench replacement for Brand or Hawes to grab boards. Odom is having a terrible year by his standards (8 and 5), but a lot of that is they just haven't figured out where he fits in Dallas. The way Collins has been able to maxmize the abilities of his role players, I have to think he could find a way to utilize Odom.
Because both would be rentals, what would we really be talking about giving up to get either of these guys? Nocioni's expiring and picks (the Speights trade picks)? Nocioni's expiring, Allen (who is actually a restricted free agent this offseason because the Sixers screwed up his rookie contract so he won't be nearly as cheap as he should be if they keep him) and picks?
