Romeo Crennel is definitely one of the biggest coaches in the NFL. The current interim-head coach of the Chiefs previously coached for the Cleveland Browns. In Cleveland, Romeo took over for one-time fat man Eric Mangini, who has since significantly slimmed down.
It looks like Crennel has a good chance to be Todd Haley's permanent replacement in Kansas City. Maybe if he gets another head coaching job, it'll give him some motivation to slim down? Probably not, but Crennel could sure use some time on the treadmill.
