I think Ritchie falls, gets drafted in the 12-16 spot.
There's gotta be concern over his determination. At 230 lbs, he's fat. That's the same weight as 6'7''-Chris Breen, and 6'8''-Tyler Meyers. And if he's not physically fit, that would explain why so many scouts say he's a beast one minute then taking shifts off the next.
He could have all the tools to be great, except for that desire to do what it takes, which in that case he'd just be a big, skilled, lazy, inconsistent player.

I've dropped him out of my top 10.
