but lillard has bigger wingspan - meaning lillard has much wider shoulders and trey's arm is long as hell.
and look at the no step vert. trey is only 29 1/2 inch. basically trey never worked out in his life. just look at the bench number. 185lb 3 times? that's weak sauce. seriously.
and no step vert is all about doing squat. there is no ifs and buts about it. NFLers have much better no step vert than NBA players because they squat to death weekly basis.
What?
I don't care about all those other measurements. The only ones that matter in dunking are standing reach, max vertical, and hand size. Lillard's longer wingspan might allude to bigger hands though, which certainly makes dunking easier. The biggest problem a lot of players have with dunking is palming the ball.
And why would you list barefoot height? Last time I checked, no one dunks without shoes in the NBA.
