If Peters is nursing an injury..........Then, sit him until he's 100%.
If he's actually healthy.........Then, sit him. He's benched..........If he complains, then let him walk....No harm, no foul. Send him on his way.
He needs to get the message that we won't tolerate "freelancing" and it's not his first time. He's been beaten too many times, so that means he's not getting the message and he's going to keep doing "his" thing.
I'm calling this.........I bet you that when he makes his next interception, he's going to make it look like he just won the Super Bowl. He's going to do some "look at me" routine and act like he's the best thing since sliced bread......You guys just watch.
