I dont know if this was the best, but it just stands out in its awesomeness for me.
March 4th 2001. My buddy, a fellow SU grad, had an extra ticket to the Syracuse @ St. John's game at MSG. I jumped on it. I dont recall how good St. John's was that year. My vague recollection was not very. But regardless, the Orangemen were at that place where they could be vulnerable, looking ahead to the BET (this was the reg season finale) and the Johnnies were essentially playing their tournament game. They were jacked, and the crowd was too.
So we go to the game. Well...turns out his Dad is a looong time St. John's season ticket holder, and an alum. So we are seated in the St John's student/season ticket holder section. 2 rows directly behind the basket.

The game was incredibly close. It ended up being a double OT win by Syracuse after Allen Griffin carried that team on his shoulders down the stretch (To this day Griff's performance that game remains one of the single most impactful...not necessarily in stats but just presence) I have seen out of an Orangeman.
My buddy and I were incredibly jacked...a bit imbibed...were able to give high 5's to Griffin and a couple other guys (Shump?)...then...we turned around. And the glares out of the St. John's faithful were intense.
Once we got to the concourse, it was fine, because the building was probably 2:1 Orange to red. But the walk up those 20 steps or so...they felt long.
