I'd really prefer a scoring big.
Scoring bigs, most of the times at least, put's opponents bigs in foul trouble, and that' a great deal.
He still has to play some decent defense (so pass on Scola), but if he'll average a double-double, gets to the line atleast 6-8 times, a suspect defense is probably a setback I'd be willing to take. So yeah, someone like David Lee is my kind of big. I'll just find a way to hide his defensive lapses.
