25. Robert Griffin III
Griffin’s story is one of the most depressing on this list. He had a magnificent debut season, setting a whole bunch of rookie records. In one win against the Eagles, the Redskins’ quarterback became the first rookie quarterback to throw for 200 yards, pass for 4 touchdowns, and rush for more than 75 yards in a single game.

By the end of the year, Griffin was 258 of 393 passing for 3,200 yards, with 815 rushing yards, and seven scores. Then he won the Offensive Rookie of the Year Award. However, disaster struck when he tore his ACL and LCL in the playoffs. This put him out of the Pro Bowl and his career has never recovered since.
