People sure do love to hypothesize about Torts retiring & who’d replace him.
Of course Meltzer is one of those, since he is such a Frost fanboy & thinks Torts has been unfair to Frost.
Torts still has a year on his contract, loves coaching, is in the middle of his project of reshaping the team, has done a good job, has given no indications of wanting to stop coaching, & management loves him.
Much more likely he signs an extension than retires or moves to the front office next season with a year left on his contract.
Whenever Torts does leave, I imagine Brad Shaw would be first in line as successor, assuming he hasn’t been hired as the head coach elsewhere.
