F*ck their feelings. These are adults. Treat them like adults. Make an adult decision. Feelings shouldn't have anything to do with it. The guy (Lewis) isn't acting like a captain/leader/team player and he should sit or be suspended until he gets his act together and shows that he wants to be a contributing member of the team.
Maybe this is Riley's adult decision, but from the info I have, which could be incomplete, it doesn't seem like it, but there isn't anything else I can do.
But you don't make a decision because of feelings.
THIS. By all means, let's let a bunch of kids hold a program and fan base hostage because they're butthurt their old buddy 'Coach Dad' got sh!tcanned out of here. GROW. THE. F*CK. UP. You're 5 games into a new season, you've sucked thus far, none of you are doing yourselves, your futures, or your teammates proud. My gawd what a pity-party.
Seriously, who can we write in the Athletic Department to voice our concerns? I want to support Riley, but this decision in particular just baffles the mind. You let this go, AGAIN, and it's clear they don't respect you one bit. Your bark has no bite, and you've lost the locker room. I'll stomach any amount of losses, if he comes out and says "For the ultimate survival and general well being of this University and this football program, I've had to make some tough decisions, and the following players are no longer on scholarship here at the University of Nebraska-Lincoln due to conduct detrimental to the state of the program, and their fellow teammates: (player 1, player 2, etc.)" Seriously, who cares one damned bit about the Johnny Sh!tstick Bowl sponsored by Monsanto? 6-7 Nebraska takes on 7-6 Directional State U, that's a CANNOT MISS right there.
Fix it, once, and be done with it.
