Really good, yes. But there are people suggesting in this thread that they should be top 5 or top 10 champ of all time which is almost all based on champ game and following year.
I mentioned the weak seeds they beat in the tourny, but they lost to probably the 2 best teams on their regular season schedule (Oklahoma and Kansas, #1 and #2 seed). They beat Arizona (#2 seed), Arkansas (#4 seed), and Louisville (#4 seed) at home, which were their best wins.
Other games against tourny teams-:
Wins - Loyola M (#11), Cal (#9), @Temple (#11), UC-Santa Barbara (#9), New Mexico St (#6), Louisville (#4)
Losses - @New Mexico St (#6), @UC-Santa Barbara (#9), @LSU (#5)
So 9-5 against tournament teams, but their best win away from home was (#11) Temple. A good resume, but considering they beat nobody in the tournament, I don't see how you can make the case they're one of the best champs ever.
