sandy, I was thinking maybe Crawford too. The irony is that I think LeVert will be a Crawford-like player at the next level.
I found a page that has way too much Michigan Basketball info and got this (since 2000):

I guess I overlooked Burke's freshman year because I didn't recall him being that prolific of a scorer as a freshman. I definitely don't recall Hardaway Jr.'s 30point scoring night either.
I didn't start religiously following CBB until I went to college (2007), so I definitely didn't watch see any of those other games.
