I would hold judgement on Buycks (and another impressive BU recruit- freshman Darius Johnson-Odom) until we see how they play against "real" D1 teams. So far, Marquette has played Centenary, who is dropping out of D1 and will have an RPI by year's end of around 340, and Maryland Eastern Shore, who will end up not too much better.
I believe both are very talented, but they are both around 6' tall, not big for a shooting guard in the Big East. When Marquette gets to the part of their schedule where they play Xavier, Creighton, NC State, Wisconsin, and then a
full Big East slate, I suspect he won't get so many easy baskets.
