Agreed on both of these posts, and I'd add that we'll need to rebound better than we did (at least in the first half) on the misses after helping on the dribble drive, which will be difficult with 1-2 7 footers on the floor for Seton Hall.
In short, if we can: (1) help without over-helping; (2) to force hand-in-the face jumpers; (3) recover to get inside rebounding position and block out SH's tall/athletic bigs; and (4) Powell has an off night shooting 30% or below; then we have a good chance to pull off the upset (if we can hit 8-10 threes).
Seems easy; I'm not sure why everyone is so scared for this game.
