Sam Bradford comes to mind for me:
Major shoulder injury in college (2009).
Severe high ankle sprain in 2011.
Torn ACL in 2013.
On the Lions Ryan Broyles can't get out of his own way:
Torn ACL in college (2011).
Torn other ACL in 2012.
Ruptured achilles in 2013.
Will he rupture his other achilles in 2014?
