i think its based on a lot of factors thats why a team doesnt want a player back, some are quite good but they dont fit the team's system.
i think Young will be a great fit with the Raps. he seems to be a good pick and roll guy, which is currently the raps are very good at. i think he is a more athletic, smaller version of amir.
If Young is as good as some think and Philly doesn't want him then wouldn't you think they would trade him between now and the deadline to extend the qualifying offer?
