The thing about a line around 10.5 is that we could lead comfortably and still fail to cover.
We could lead by 10-15 throughout and give back a little in garbage time while being indifferent about scoring.
We could lead by 7-10 throughout, get into the "foul vortex" at the end where SH will try to score, but will give up on fouling us if the lead is 9-10 under 30 seconds, and we'll just dribble it out.
If the game is remotely competitive down the stretch, you're relying on luck to push the lead to 11.
Edit: one way you could play this is to wait for us to get a small early lead and then take Seton Hall +12.5 or whatever. They'll cover in any non-blowout.
