Welcome Chuck - I'll weigh in. For the most part, you'll see a very similar D as SFA. Lots of pressure on the guards and no doubt we'll double down on Tilmon if they do feed it low. With the pressure we are prone to a talented guard driving to the rim as we do not have a rim protector, but when we're on, we do tend to draw more than a few charges. We are #22 in turnover margin in D1 and #8 in Turnovers forced per game (SFA being #1 forcing 22 against our 19+). The advantage for you is that you've now seen this pressure twice already - so you will be familiar.
BU is good at scheming so you can bet (as former coach) he's studied the SFA game, and is very familiar with WVU methods. Expect to see much of the same as we do go 9 deep with alot of guard pressure. We tend to hedge/assist on high post screens but keep the guard on guard. The guards switch with each other freely as we don't lose very much in D amongst our top 4 guards.
I'd say most really like BU as a person and his approach. We went from "nice guy" coach in Groce to 'push you to your limits' coach BU - that is what I would want for my kid. Our freshman are far and away more prepared early in the season than they were in the past. We feel we should easily have 2 more quality wins under our belt as we had 2 poorly executed inbounds plays in the last few seconds of games (4 seconds, leading, and 33 seconds tied with ability to take the last shot).
