He does seem a bit like a douchebag.
During Ray Rice's last season he started acting crazy.
He was spitting at opposing players and getting in fights.
He was injured and 10 lbs overweight.
Coach Harbaugh said Ray wasn't fat (fat index unchanged) and the extra 10 pounds was muscle.
That told me Rice was on something because a 5' 7" guy who played D1 and NFL for 6 years doesn't suddenly put 10 lbs of muscle on in mid-season.
Sometimes athletes take steroids, HGH etc to heal (remember Andy Petite).
I think that's why Rice was off the beam in the casino (he fought a security guard before wife incident).
I saw the same thing with Kelce the last few games,
He's been a maniac on the field and sidelines.
Before Reid incident I thought to myself ("Kelce is cranked")
