When you look it from Ben's side of things, staying sidelined for a whole 1st year makes you ineligible for the ROY if you change the rule. I get it.
BUT
Ben had the chance to pump his body up whole season instead of playing games. He got ready for the action more than someone from 2017 class.
AND
People miss chances for success when they get injured. Deal with it. Injury is a part of this profession.
I think changing the rule is the more just thing to do. Above all, being this great athletically, this ready to play straight away, not hitting a rookie wall is something absolutely special for DM.
