Some of these just live rent-free in my head. YMMV
For "role" players:
Jamal Coombs-McDaniel averaging 21/gm over a three-game stretch in 2011 comes to mind.
Rash with his three barrage against 'Bama
Denham scoring 101 points in high school
Eric Cobb going for 13 and 13 beating Cuse in one of our last-ever meetings
Brimah's 40
Ricky against AI as a Freshmen and 13 against Duke
Toraino in the BET as a Freshmen
Cup Cormier vs. NC State in his one year here. Think he had 14 or 15 and was unstoppable off the bounce. Everyone thought he should start over KO who was really struggling.
Doug Wrenn got one start against GTown. I think he came out hit an ill-advised three, then an alley-oop, then later Khalid threw one of the glass for a dunk. Thought Wrenn was going to be the answer and our next star. Seemed like the next day he was back in the doghouse and gone at the end of the year.
Tony Robertson - I think versus BC? where he had back-to-back monstrous tomahawk dunks
Hilton - There was a game against Seton Hall where he blocked like 9 shots and injured one of their players. Fans were irate. So he just blocked more shots.
For major players:
Donyell's 42 and 20-20 Free Throw Game
Ray 36 against UCLA.
Khalid's first game against Yale. This one is burned in my memory because he just dominated and commanded the floor the first time he put on the uni.
Caron's 34 against Maryland and his triple-double freshmen year where he threw the behind-the-back pass while falling out of bounds. Special mention, too, for the game against Vandy early in his sophomore year where he literally stole the ball three straight times for dunks and Kevin Stallings looked ready to retire from coaching.
Ben's 36 against 'Bama
Charlie V - after being suspended, finally getting his first minutes and hitting like a 26 foot 3 the first time he touched the ball.
Nadav vs. GTown and Mourning
Deandre Daniels vs. Iowa State
Thabeet - Triple double against Providence where they were afraid to shoot.
AJ Price 36 against Marquette and that ankle breaker
Jeff Adrien - Freshmen year against Nova he just physically dominated. One play I remember is him just ripping the ball away, knocking their guy to the ground, and him just stepping over him.
Kemba's first game against Kentucky when we went on like a 20-2 run.
Bazz versus Nova where he hit like 3 or 4 straight deep three's when it looked like we were going to squander the lead
Adama hitting three's against Miami to start off the final four game
Donovan against Illinois
