Coach

Coach is one of the four playable survivors in Left 4 Dead 2. Coach was a high-school football instructor for a well playing team, but he suffered a nasty knee injury. Ironically, he's now a health teacher pushing 40 years old, but he's gone to seed since his collegiate glory days. The zombie apocalypse makes him wish he'd watched his own fitness more closely. Faliszek says Coach has "a great hatred for a few of the zombies—the Witch in particular," but naturally, he wouldn't explain why. He appears to be Bill's replacement.
