There will always come a time when the opponents guards are able to break any press and set-up their half-court offense. In so doing they negate the uptempo teams into having to play half-court basketball. If an uptempo team cannot be efficient in their own sets they end up losing.
Take a look at the list of
National Champions. Pick out one team that won the National Championship as a purely fast break team that pressed the entire time. The closest team to do that was Phi Slama Jama with Hakeem Olajuwon and Clyde Drexler, but guess what...they lost the National Championship game to a team that controlled tempo and didn't turn over the ball.
The Gophers can win more than they lose playing an uptempo game, but come tourney time they will run into teams that will control tempo and the Gophers will have to be able to be successful in all types of tempo in order to move forward in the dance. A great example of a team that is efficient in different tempos is Coach Izzo's Spartan teams at Michigan State. He also runs great sets out of his half-court offense that isolates a teams weaknesses. He's been successful precisely because his teams are well balanced and can play at different tempos. If Tubby can get this team to play at various tempos then he'll have a team that will go deep into the tourney. We haven't yet seen what this team can do when they take on a team that isn't bothered by pressure on their guards. We'll know much more after the Gophers play Duke. Until then, I won't get too excited about beating the "Little Sisters of the Poor."
