I mean if there's one position in hockey aside from the medical staff that fans truly have less knowledge about than coaches, I don't know it. It's obvious by the Jack Adams which in my lifetime is just the "Most Improved Team Award" or better, "the media's preseason bracket breaker."
With that said, from that list, I'd go with Babcock. He managed to get a lot out of those aging Red Wings teams, and I think he managed to get a lot more out of less than his successor in Toronto. Plus he's actually a smart guy, so there's a chance he's learned from his past mistakes.
Quennville has the better resume no doubt, but after so many other humilations, I really don't want the Rangers to give me another huge reason to resent my own fandom.
