The missed dunks were backbreaking, frankly, but I think just a fluke. The softness is a bigger issue. It was really epitomized late in the game when he and an OSU player went up for a 55/45 ball, Robinson had slightly better position, and the OSU player got it from over his back and Robinson ended up on the ground. Oweh is probably the closest thing we have to an enforcer, physically and temperamentally, but he's really not one.
I don't want to project too far ahead, but given how nice a guy Pope is it'll be interesting to see if his teams have enforcer-type guys on them consistently. I think back to Cal's first season yelling at the Louisville player who got into a scuffle with Bledsoe, that he messed with the wrong mfer! Pope obviously wouldn't do that, but it's also obvious no one on this team would warrant him yelling that about.
Edit -- I left out Kerr, who clearly has the most aggressive "enforcer"-type personality. But he's not imposing, he plays like 15 mins a game, and who knows when we'll see him again anyway with his injury.
