Don Juan - spot on. In the case of Geben, unless he catches up to the speed of the game this year [and there's prolly a 50/50 chance of that] his role on the team will be limited to 4-5 minutes in the first half to help keep Auguste out of foul trouble and help keep his legs for the second half. In the case of Colson, he doesn't belong on the court yet in games like these. He will contribute a lot next year & has some great skills, but his defensive positioning is terrible and he doesn't yet understand the flow of the offense. Also, anyone complaining about Vasturia getting too much time, doesn't watch the game closely. He's our second best defender behind Jackson - perfect footwork, never out of position & asked to defend the oppositions best wing player every game. Even when he's not scoring, he's a big part of why this team wins. Last night he legitimately was struggling on the offensive end & Brey gambled that VJ's offense would offset the loss of Vasturia's defense. The gamble paid off [and was probably made given that UNC is a pretty terrible shooting team]. But you will rightly see Vasturia on the floor for a minimum of 30 minutes every game this season.
One additional point. Almost every coach will tell you that 'rest' is over-rated. Yes, bigs tend to need some rest & I think getting Pat back to 35 minutes a game would be good [so please Burgett, start getting back into the shape you were in at the beginning of the ACC season last year], but having your 1, 2 & 3 play 35+ a game is not only not a problem, but common practice even in the pros. There are a ton of teams that have won the NCAA with a very short rotation - in fact the most recent UCONN championships came with teams that only had a 6-7 man rotation. It is a myth that guys can't play 35+ minutes all season & still compete for the NCAA. Further, that has not been Brey's problem in the tournament, athleticism has. And for the first time since his first couple of teams, we now have the athleticism to compete in the tournament.
