Everyone would be mad still, yes. I'm going to be mad about this til my dying breath.
But I might at least begrudgingly hold my nose and accept that he'll probably be back on the sideline next year if he just came out, admitted it was a panicked, boneheaded decision, and that he'd learn from it and not do it again. Instead, we have every reason to believe he would do the exact same thing again despite it making no logical sense whatsoever. If he's stubborn enough to defend an indefensible call, he's stubborn enough to do it again just to spite everyone even if deep down he knows he blew it.
As for replacements, it actually wouldn't be the worst time in the world to fire a coach. Paul Lapolice is available, as is Corey Chamblin. Scooping Claybrooks from the Stampeders would have the added benefit of weakening a rival.
