Campbell has that team playing with energy and a killer instinct, absolutely, and he deserves every bit of praise he's getting. But GM Brad Holmes has been killing it with his draft and signings. He's injected the right talent, often elite talent, into every position required and is taking bold swings that are paying off. Conventional wisdom said the team didn't need Gibbs and Montgomery but here we are, with the Lions dominating the run game and having two guys fresh and pounding at every phase of the game. Brilliant.
Unfortunately due to the molasses nature of hockey drafting, guaranteed and long contracts for anyone remotely good, and usually meh free agency there hasn't been that kind of immediate impact for the Red Wings. Overall I've liked the steady hand and drafting of Yzerman, I see the vision, but the free agency and trades have been a mixed bag at best so we're left with a middling roster that will steal games here and there but ultimately needs the high draft picks to hit, and hit hard, or else we're going to be cycling coaches for the next decade.
The Lions didn't just get a coach with a great gameplan and attitude, they also rebuilt core components of their team in the span of a few years which is entirely possible in the NFL and dreadfully, boringly not possible in the NHL.
Honestly the older I get, the more I dislike the incredibly slow build of teams in the NHL. Without one of two significant draft gifts, McDavid or McKinnon level, you're staring down the barrel at 10 years of "We're building something!" games rather than believing you can actually get hot and win the whole damn thing.
I'm not sure what the answer is, but this is my long-winded way of saying I'm not sure cycling coaches is going to do much for this Red Wings team other than give us something new to talk about.
