That has nothing to do with Caldwell. Give me a break, man...lol. These guys age in a snap.
I did say it's not on Caldwell, but there are enough similarities between 2013 Ravens and 2014 Lions to make you pause.
Both had decrease across the board in the offensive department. QB play, RB play and Oline play all decreased while he was a coach.
This year QB play, RB play and Oline play all increased to 2012 levels for the Ravens.
I'm one that tends to put more blame on the players than coaches...but the similarities are slightly concerning.
