Yellow Jackets? A bunch, but probably less than I would have expected.

I wouldn't have even thought about it if I didn't find COMC. I've got the autographs from most of the Tech baseball players, and cards from almost everyone who has a minor league card as well. Basketball and football, I've probably got 1000+ cards of a hundred or so players. I'll have to catalog all of them someday and search out the ones I haven't stumbled onto yet. I know I'm missing a Chris Reis card; the only one I know about was from the 2009 Saints Super Bowl set, from when he grabbed the onsides kick after halftime.
