He measured under 8'10" in standing reach in spring. Randle is wide, hence occasional Zach Randolf comparison, but not really long.
We'll find out for sure at the NBA combine, but at the Nike skills Academy, which was the last time he was measured, he measured at 6.10", with a 7 ft wingspan, and a 8'10" standing reach. What makes Randle stand out is number one, his confidence, and his ability to score from the outside as well as inside. He's an excellent ballhandler as well. Most of his turnovers come from trying to make passes that just aren't there, but he was a good passer in highschool. Now you may not see him do much scoring from the outside, but that's by design in Calapari's system. No on knew that Cousins could shoot the ball either, because Calapari wouldn't let him leave the basket on offense.
As for Parker, if your finding things about him you don't like, then I just don't know what to say. He's without a doubt, the most skilled player of his size I've seen in a very long time. He's an outstanding ballhandler by the way. He can score inside, outside, midrange. He has turnaround jumpers, fall away jumpers, he can score with hook shots with either hand. He has excellent dropsteps in the post, and moves to go with them. He can pullup on a dime and score with a jumpshot, or at times a floater. Add in that he's an excellent rebounder, and I frankly don't know why anyone would be critical of him offensively. Five years from now, Wiggins may be the better player, but if you pick Parker now, you'll have one of the best SF's in the NBA the minute he sets foot on the floor. Just because he's playing a lot of center and PF for Duke, doesn't mean he can't play the SF position. Which is what he played most of his highschool career.
By the way, I'd be very happy with Wiggins as well.
