I think you're judging Craft based on the team's play during his senior season. And this team cannot be judged until B1G play starts. The schedule so far isn't telling us much.
His defense was great, but he's also OSU's all-time assist leader, and he was a key player on team's that made deep tourney runs.
He was a great basketball player. If you don't get it, you don't understand the game.
