Wow! I hadn't seen the Carroll or Belichick news, yet. I had heard reports about both of them being on thin ice throughout and even before the season. I think owners are just becoming really impatient, but there probably is some player empowerment stuff factoring in as well.
I feel like the Cowboys are more likely to blow it, but the Steelers are more likely to steal it. I'll take Tomlin's Steelers as more likely to pull off the upset.
