The Steelers are still barely in contention for a playoff birth this year after playing their (technically) 3rd and 4th string QBs, backup running backs (their starter going into this year is a backup, quite honestly) and backup receivers. Tomlin won’t win it but this is coach of the year territory. There is no way a season like this would happen in Dallas (we have the evidence). Garrett would likely lose every game without the starting QB, the other injuries would have us in contention for the #1 overall pick.
In my humble opinion, there is NO WAY Tomlin is available.
If the Steelers ownership (the same family who has had 4 coaches in the long history of the franchise) decides they want to part ways with a coach of that caliber, it would be the shocker of the year. (Next to the Luck retirement)
