The important number, the number that will likely decide the game is 4. 4 fouls, 2 each on Morris and Carter by halftime. While neither can shut-down a guy of Tuttle's caliber, Wichita State probably can't win with anyone else guarding him. Wessel is too small, and the rest are still unprepared to guard an elite or even good player.
If the half-time whistle blows with Carter and Morris having less than 4 fouls between them, it should be close. Pick up more, and it gets really difficult. The other factors will make a big difference as well, namely shooting and TOs, but the Shockers will need to convincingly win those to overcome an undefended Tuttle.
One problem for the Shockers is their tendency to go cold. When shots are falling they look unstoppable offensively, but this entire season I've felt the offense relies a little too much on the threat of the 3. When we go cold from outside we don't really have the size to switch to bashing down low or the ability to score consistently off the dribble. Hit a few threes, and then all of a sudden lanes open up and Carter can go to work 1v1, which our usually excellent passing can exploit.
We cannot have those one of those 4+ minute cold streaks in this game. We don't need to shoot 45% from beyond the arc, but we do need to shoot well enough that is a threat.
