I really can't imagine anyone "controlling" a match against Mack this year and I have seen many of Mack's matches and a few of Borschel's.
The most impressive thing about Mack's season so far is that he has not been taken down. Let me say that again -- he has given up ZERO offensive points against very good competition.
At the beginning of the season Koll said Mack may not be taken down at all, the entire season. I thought he was crazy. I don't anymore.
