Ray Lewis
The Ravens won the Super Bowl in 2001 as Lewis showed why he was one of the NFL’s most important players. The linebacker earned five Pro Bowl appearances as he made 69 consecutive starts for Baltimore. He was a wrecking ball of destruction who stayed on the field thanks to insane durability.

But then he dislocated his shoulder in an innocuous moment that came out of nowhere. This contributed to ruining the Ravens’ Super Bowl defense because he was a key cog in their system. They finished 7-9 and they disappointed their fanbase after one of their greatest-ever years (via CBS News).
