Personally, I'm not a fan at all of removing the names off the back. Kids these days want recognition. That's why many recruiters take kids into the stadium and show them their names on the jumbotron. Will it hurt recruiting? I doubt it, but it can't help it.
As far as the other changes...I'm indifferent. Coach Gill is just changing the uniform to look more like what he had at Buffalo. That's his perogative and no different than what Mangino did (block "KU" on the helmet ala OU) his first season.
I think coaches do that to mark their territory - show they are now in command.
