Mark Sanchez, New York Jets, 2009
Sanchez went to back-to-back AFC Championship appearances in his first two seasons, but make no mistake: the Jets won games in spite of their struggling young quarterback, not because of him. The USC product threw 69 interceptions in just four years in New York and was released following the 2012 season; after finishing the year with 13 touchdowns and 26 turnovers. He began 2017 as the Chicago Bears’ third stringer before going down with a neck injury. He is now a free agent and was recently suspended for four games for violating the league’s performance-enhancing drug policy. Hardly the type of production you expect from the 5th overall pick.
