You'd take Biedrins/Childress ahead of Allen?
Yep. I know Biedrins has tailed off, but he was basically a double double center for 3 years. That has a lot more value and worth than a defensive guard.
Childress is a bit closer obviously as he left for Europe and has been pretty poor since he got back, but he was also much better than Allen at the start of their careers. Pretty interesting question actually.
In another year or two if they keep trending like they are, I'd take Allen over either, but at this point, I'm taking the guys with the higher peaks.
