While I loved Frank's substitutions, I'm not sure why KenPom calls them "brilliant." It seems pretty basic to me...you sub Beasley in during any dead ball in which an offensive posession seems likely to follow (ie, out of a timeout when you get the ball, off an aTm turnover, before an opponent free throw) and out during the opposite.
I guess we don't see many coaches do that type of thing. But to me that says that a lot of coaches are actually pretty dumb (which is another theory of mine), not that Frank is brilliant. But hey, at least he's brilliant when compared to other coaches, which is what really matters.
