You guys are thinking small. That's one, maybe two epic threads the week he signs. And then years of the same old shit. Just imagine the first time the new manager benches a kid after a good game in preference for a veteran. Or the first time he pulls a starter too soon, or brings the "wrong guy" in from the bullpen. Or a veteran slumps and gets some leash to work it out. There's years of entertaining threads just waiting for a new guy to tap into.
Plus if he's some other ethnicity, we'll have all new food choices to riff on!
