Tepper is doing tremendous damage to himself and the organization with knee-jerk tantrums like this.
No self-respecting coach will take that job at this point.
It goes deeper than just knee jerk reactions. He had plans for a multi million dollar practice facility/headquarters in South Carolina and pulled out mid-construction due a disagreement with the town. He is a frequent meddler, even instructing Ron Rivera to convert to a 3-4 defensive scheme his last year here because he was comfortable with it because they did it in Pittsburgh.
They cut a Guard 2 weeks ago, and local media joked that his wife (a 33 year old woman that he just married a few years ago that has been elevated to a FO position) was sitting in on practice watching OL drills.
Not to mention he owns the MLS team here locally. They've played two seasons and he's fired two coaches, the first of which wasn't even allowed to finish the inaugural season because he was so outspoken over the ownership.
Tepper is god fricking awful.
