It's a good idea, but IMHO it won't (and shouldn't) happen unless and until GMTM is canned -- which, IMHO, won't (and shouldn't) happen for at least one more year.
Watching this embarrassing performance in TB -- I have to believe that GMTM is going to fire DDB. If that's true, then I think GMTM gets to hire a new coach, and if there is improvement next year, GMTM and the new coach will get at least another year thereafter. If GMTM hires a new coach and there is no improvement, then they're both gone after next year, and it will be time to bring in a president of hockey operations to hire the new GM and, unlike PLF, stick around to oversee matters. Same outcome if GMTM brings back DDB and the team is terrible at Xmas -- both are gone and a president is brought in to hire the new GM and oversee matters thereafter.
If DDB isn't fired by Wednesday at the latest, we have a major freaking problem.
