The Walter McCarty jersey gets the nod over the Dana Barros jersey every game. There's a lot of history there - I don't think I've seen the C's play without it, although their overall record has a winning percentage of somewhere around .333.
The bad jersey collection is at about 20, with gems from all sports like:
Elvis Grbac
Rick Mirer
Tariq Abdul-Wahad
Mike Gminski(!)
Dana Barros
Chris Canty (Pats DB)
...and many more that I can't remember right now.
For the record, I'm not a Pacers fan, but I can appreciate what Bird is doing with the team, and I've always enjoyed watching Jim O'Brien's teams play. There's also the slight hope that the Pacers sneak in for the 8th seed in the East and play the Celtics in the playoffs, and then I'd be guaranteed my seats.
