For actual brawling I see a bunch of good choices here.
I'd pick Jim Rice. One brawl I saw he wasn't fighting, but was just tapping shoulders and pointing to the dugout. Nobody swung, they just left.
I also heard a story about Boog Powell ending a likely bar brawl by stuffing a local connected hood into an ice cooler headfirst. Yeah, I might want him too
That Schmidt fellow sounds both damn tough and a bit crazy, a fine combination.
