Robert Sacre, the big man of Zaga is a menace on the boards. Burrell, Evans and Brownlee have to get up for him and really contain him because he is a force downlow.
Also the guy who has to come up huge on D is Boothe. Stockton of Zaga is like the white version of him....though he is a freshman and will be prone for mistakes on the big stage. Stockton is a sparkplug player who can make some very good dishes downlow if given the chance too. If Boothe brings his great defensive game, he could get the Zags to make turnovers.
Its a winnable game. Mark Few is a slick coach with alot of tourney games under his belt. Zaga will be more experienced heading to the tourney game no doubt but St Johns is more athletic and if Hardy has his A game, they will have no answer.
