Ray Rice isn’t in the NFL because he KOed his wife.
He isn’t in the NFL because the NFL doesn’t think he is a good enough player to deal with the backlash of employing someone who KOed his wife.
If Ray Rice was Adrian Peterson, he would be in the NFL. If Ray Rice was a All-Pro QB, CB, Pass Rusher, LB and etc he would be in the NFL.
But, Ray Rice is a running back that most people believed was on the downside of his career, that is why he isn’t in the NFL, nothing more, nothing less. Here is his wife Janay Rice doing her best on ESPN “Outside the Lines” to try make NFL GMs give him another chance.
