let's play a game of "which is more likely"
A. FO realizes Granlund is a super good, important player and only Sullivan is standing in the way, thus they fire Sullivan and Granlund goes on to achieve NHL greatness surpassing our wildest imagination.
B. Granlund and his cap hit are moved out in a deal that brings back 100+ pt Erik Karlsson and Sullivan remains coach.
Not saying Sullivan isn't a problem, he 100% is, but let's be realistic for a moment - Granlund is hardly the player that's going to tip anything against Sullivan. He was a dud here. He was moved. That's life. I still do that trade 10/10 times.
