I'll concede that the block out point is actually a fair one, though for different reasons . Part of the reason Love is a great defensive rebounder is ironically how he'll cheat on who he's defending, leaving early to get into boxout position (this can be bad sometimes when he leaves a guy open, gets in position, and the guy hits an open look...I remember LeBron lighting into Love for doing this too much in a season game against the Raptors a few years ago). From what I've seen of Wade, he won't leave his man like Love does, instead staying on the ball and using his superior lateral quickness to cut off angles. This makes him a better on ball defender, and he will contest even on the perimeter, which would naturally leave him in a worse spot to grab boards. Seems there are fewer rebounders these days who also play good defense (as in Rodman, Russell etc of yesteryear), likely due to today's pace and 3 point shooting. There's much less of a time window to try and rotate and close out on shooters while also then running to get into boxout position. Bigs can't sit completely in the paint anymore like they used to.
