Andrew Luck shocked nearly everyone in the NFL with his decision to retire Saturday, including his former coach Bruce Arians.
Arians—who was the Indianapolis Colts offensive coordinator and interim coach during Luck's first season in 2012—discussed the surprising news Sunday, via Lorenzo Reyes of USA Today:
"Knowing his toughness and his mental toughness, this does surprise me. Something has got to be wrong somewhere, because I know he loves the game so much. I did two of their games (as a TV analyst) last year and he was running off the bus to come say 'Hi' and tell me how the team was doing, the young receivers and how excited he was, so to see it was very disheartening.
