When was the last time a QB suffered an injury as devastating as a torn ACL and came back to win a Super Bowl?

Try never. In recent history, the last 5 QB's who suffered the same injury as Wentz was Carson Palmer twice, Donovan McNabb, Philip Rivers, and Robert Griffin III.

None of them were ever the same after the injury and in Griffin's case, it ended his career.

Carson Wentz will be lucky to have a 5 year career. He will never win the Super Bowl.
