carr has no chance of ever being fired. he's had too many overall winning years and runs way too clean a program. michigan was reluctant to dismiss tommy amaker, who accomplished absolutely nothing in ann arbor.
that said, there is a chance carr resigns. thats a possibility. but he would never be fired or pushed out.
sad thing is, michigan has looked like shit. and yet they will still probably beat ohio state this year by 10. that will probably be the only thing they accomplish this season.
