The magic number is 22 wins. Anyway you slice it, 22 wins means we beat some quality resume builders to get there.
I do agree, we lack a signature win so the Nova game will be huge. But if you look at the teams around where Lunardi has St.Johns, almost all of them lack what we are calling a "signature win".
If we can beat Xavier again and Georgetown once that will give us 5 top 50 wins. Then we need to beat Seton Hall and Marquette on the road, plus one win in the Big East Tournament to get to 22.
