Crabtree is nowhere near the athlete you make him out to be and he won't do anything near what he has if he isn't in a west coast offense. His height/weight is comparable to Andre Johnson, but Johnson is MUCH more athletic.
Maclin is a fairly polished WR and will be a #1 before Crabtree IMO. He has good size and is far more athletic than Crabtree. Plus, he's a better fit for intermediate/deep passes than Crab.
edit: That list of teams he'd be #1 for is way off IMO. The guy is gonna go in the mid to late 1st round--where he should go.
