Yeah that's weirdness for sure. I don't know if I would vacate Tomlin, but I would certainly have a talk with him about having more firm a hand on his coordinators dealings. The HC is supposed to be a leader of men, and sometimes that means pulling someone up by their shirt tails. Seemingly he let Haley have carte blanche with the offense.
I didn't think I'd want to either, but he has some serious deficiencies at managing a game. Weird calls, questionable clock management, failure to control the locker room, coaching down to the competition, failing to have his team ready to play, letting the defense make average QB's look like Pro Bowler's (Brett Hundley and Blake Bortles for example this season alone), and more.
All of this while having arguably the most powerful offense in the NFL, and one of the best offensive lines in the league. What does he have to show for it? A bunch of losses to the Patriots.
Joey Porter and Carnell Lake, while beloved former Steeler players, just are not coordinator material. Proof is in the performance, and both of those positions have been on a downward slide since 2009.
Maybe Tomlin is playing them like he played Arians in 2011, and will let them go in a few weeks. If so, then shame on Tomlin for lying.
Then again, maybe this 'report' is false and Tomlin has not told anyone on the defensive coaching staff their jobs are safe for next season.
