Every time we play man we switch screens and it kills us, our bigs can't keep guards in front of them. I don't think we need an entire team of jackson emery's but at least a couple that can shut star players down. Coach Rose continues to produce 20+ win seasons, so he knows best, but think how much better Jimmer was because Jackson handled all of the tough defensive matchups. That turned into a rant. I apologize to anyone that read this😆
