I'd have to put a LOT of thought into this to come up with a list that made me happy, and even then it might be impossible, so instead of doing that I'm going to just vomit out whatever is stored in my mind right this minute.
I think its hard to compare some of these games. Regular season games have been emotionally just as satisfying as tournament wins to me, but in the tournament you get the added bonus of being excited for another upcoming round. Also, my favorite tournament historically has always been the Big East tournament and not the NCAA tournament. You got better games in the Big East tourney. For this reason I like the idea of splitting the games into four lists. Also, I have a hard time ranking the championship game as my favorite game ever. It was the most significant, certainly. But I didn't enjoy it as much as some of the others. First because I was worried they would lose. They had a big lead which slowly dwindled throughout the game, as a fan those are the hardest to watch. And second, because even though I was very happy they won, I was also a little sad that the season, and the great ride we had, was over and there was no more basketball to watch.
My list comprises the 86-87 season to now, because that was the year I really started watching SU.
Full disclosure, I know there are big games I'm forgetting ALL over this list. Feel free to add some I'm forgetting.
Georgetown games (always the best regular season games)
1) 1990 JT ejection. Not sure I've ever been happier in one moment of watching basketball than that.
2) 1996 blow out of the Iverson GTown team, which was revenge for them blowing us out earlier . . . love that 96 team.
3) 1989, I hope I'm not confusing this, but I think SU had a big comeback against Gtown this year, maybe the most fun SU team ever.
4) Was it 2007, when SU was on the bubble and Gtown was in the top 5 and we beat them?
5) Donovan McNabb Game
6) GMac buzzer beater
Thinking it through, a lot of the really great games were ones that Gtown won . . . damn them.
Other great regular season games
1) Sherm Douglas through the legs full court pass in SU's revenge destruction of Indiana . . . I hated Indiana and Knight and wanted that one bad.
2) SU beating Pitt in 2003
3) SU's very surprising (to me) win against #1 UConn in, I think, 2004.
4) SU's rout of top 5 Nova in 2010 to take #1 in the polls.
5) Beating #1 Louisville at Louisville in 2013
This was the hardest one for me as there have been thousands of great games. Those 5 came to mind. I'm absolutely sure I am missing a lot of great old games.
Big East Tourney Games
1) The GMac run. Can't pick just one game. Not sure anything tops that for me.
2) 6 overtime classic against UConn
3) SU finally beating Gtown for the title 1992
4) SU's Big East curtain call where we beat Georgetown one final time. They were the top 5 and just beat us, 2013.
5) Ryan Blackwell buzzer beater to beat St. Johns 1998
Think about all those great moments . . . nothing will ever beat the Big East tournament in NYC.
NCAA Tourney Games
1) UNC 1987. In my mind this is a program turning point. I remember people losing their minds with happiness.
2) Georgia 1996 . . . love that 96 team.
3) Virginia last night . . . wow.
4) Kansas 1996 . . . man I loved that 96 team.
5) OSU huge comeback with the press, GMac started hitting 3's once he got bloody in 2003. In my mind I liked this slightly more than dominating 1 seeds Oklahoma and Texas that year and Indiana in 2013.
2003 Championship has to be in a class by itself. It was a few minutes of joy when GMac hit the threes and then an hour and a half of agony waiting for the buzzer to sound.
