I've seen written here that this year's split was 60/40 St. John's fans.
I was at last year's game and thought it was even better for us, 65/35, I guess the difference is that this year they came in ranked #1 and this game was close to a sellout while last year's game was not. Neither year did their fans seem as loud as they have in years gone by (that's a good thing).
Figured this year with us having Rick Pitino and not CMA, we would have at least matched last year's %'s.
I know it is hard to guess exactly what the breakdown is, but I remember last year feeling really happy not being outnumbered.
