I was just watching part of the Florida-Kentucky game. First time I've seen Cousins play.
Physically, he looks a lot like Eric Dampier. In terms of quickness, mobility, jumping ability. Overall athleticism. That lack of elite athleticism will likely hold him back some at the next level. Reminds me a bit of Dampier with his rebounding and grittiness too.
Cousins should be a very good player. Skilled and likes to play in the paint. More skilled than Dampier was during his college days. Looks like Cousins could have an Andrew Bogut type career.
