12. Mark Schlereth – Denver Broncos:
Schlereth is a legendary Bronco who played with John Elway during their Super Bowl-winning runs of the late 1990s. What he is not legendary for is his love of the now-banned chop blocks.
He and his Broncos linemates were notorious for targeting opposing players’ knees, and they rarely hid that fact. In fact, Schlereth once said, “they were throwing 15-16 cut blocks a game. We were throwing 40.” Lovely.
At least that practice is outlawed in the NFL nowadays.
