Not really on Keenum. Basically he illustrates to stop putting everything on the QB. The difference was Crennel coached a better D result than Wade. Keenum's rating was down (78.2 to 72.2). 2013 Keenum wasn't good enough to overcome the 24th ranked D. 2014 his same performance was good enough to win with the 7th ranked D.
Well atleast you will have to give you' got to give BOB this much credit, he didn't put Keenem in positions to throw a bunch of INTS and take 20 yd sacks. So the defense could control the game. With Keenum at QB BOB realized that sometimes a punt is your best friend.
