Chiefs running back Peyton Hillis shot back at former Brown teammate, offensive lineman Joe Thomas after he told reporters in Cleveland on Wednesday that Hillis didn’t always play hard during his time with the Browns. He also accused Hillis of creating a “toxic” environment in the locker room by putting his contract situation ahead of the team. Hillis was asked about those comments yesterday and responded by saying Thomas was like a “crazy ex-girlfriend.”

Hillis missed six games last season for a variety of injuries and illnesses including strep throat. Thomas was particularly critical of that one.

“You think strep throat and I don’t know whatever else injuries he had should keep you out of an NFL game? Or several?” Thomas told reporters in Cleveland. “All I know is (center) Alex Mack had appendicitis. His appendix blew up and he played.”

Hillis had one productive season in Cleveland, 2010, in which he posted 1,177 yards and 11 touchdowns and appeared on the Madden NFL-12 cover. He then rushed for 587 yards in 10 games in 2011.
