I don't think Camby could play with Tyson Chandler, maybe on the last possession, or certain situations like that, but not major minutes.
While a player like Mahimi, would be able to play with Chandler or Amare.
Camby is a veteran but Mahimi is much younger, if they are both the same price, I do not know who should be the better target.
I love Camby, never wanted him to go, but if he can't play with Tyson Chandler together efficiently, I don't know how much better it makes us.
It does add to our depth and keep us fresh, with spreaded minutes.
If Melo cannot post up with Tyson Chandler and Amare, I am not sure if he can do the same with Camby/TC/Amare.
