I agree. I have been trashing Thacker since he got here, but I'm beginning to think that he might have been a victim of poor leadership. That said, the D has to keep it up or there's zero chance of him getting out of the sh** house. You can't total erase the previous 3 years, but if the D keeps this up, one can only assume that the changes in leadership allowed him to finally flourish.
Honestly, even with good results, I think the only chance he has to be retained is if CBK gets the HC gig. A new HC (not CBK) would likely want to bring in his own DC. So he's likely fighting to be a DC elsewhere vs a demotion to a position coach somewhere.
