A former third-round draft pick of the Seattle Seahawks in 2011, John Moffitt was a star back in college for the Wisconsin Badgers, and started nine games for the Seahawks as a rookie before being injured against the Baltimore Ravens.
Moffitt's career ran into more trouble when he ran into trouble with performance enhacing drugs, and he was suspended for four games as a result.
