Here are my thoughts about wanting and likelihood of getting (taking into account the person's desire to come here and Lou's willingness to hire them) each coach besides the actual hydra mentioned in the poll:
Adam Oates: Since Oates has been brought in by Lou to try to bring some good out of this disaster of a season, Lou will probably at least consider him for the head coach position. However, hopefully Lou will look at the terrible job Oates did as head coach in Washington and how Washington has done a one-hundred-eighty since Oates left and resist the urge to reward Oates by giving him the head coaching position. Ideally, Lou will only keep Oates on in an assistant coach capacity if at all. If Lou offers, Oates would almost certainly take the position, because he will want an NHL head coaching job, and he can't really be too picky after the debacle he created in Washington.
Scott Stevens: I like what I've seen from our young defensemen since he's taken over that, and players like Larsson seem to have a good relationship with him. Lou and Stevens definitely have a mutual respect and trust, but I'm not even sure that Stevens would want a head coaching position. He might just enjoy being an assistant coach as long as he feels that his ideas are listened to and taken into account. There is also no sample size by which to judge Stevens as a head coach in the NHL. He could be great; he could be terrible. That would be a risk for Lou in hiring Stevens as head coach, especially since if Stevens turns out not to be a good head coach, he would be put in the awkward position of handing Stevens the pink slip. Stevens might be better off in an assistant coaching capacity, but I'd rather Stevens get the reigns than Oates. Hopefully Stevens is kept around as an assistant coach, but Lou hires somebody else to take on the head coaching duties. If Lou offers the post to Stevens, he will probably accept either because he wants to be a head coach or out of loyalty to Lou and this organization.
Paul MacLean: MacLean had a pretty successful first two years in Ottawa (being nominated and then winning the Jack Adams), so that might impress Lou, and it is at least NHL experience and some positive track record. MacLean also worked as an assistant for Babcock for a number of years (including in 2008 when the Red Wings won the Cup), so that's a valuable education to draw on. MacLean did seem to emphasize defense a lot even if it led him into a conflict with Karlsson and some other stars with the Senators, and Lou is a defense-first kind of guy. The problems with him is that he did get into conflict with players and that Ottawa did turn around after he was fired, so that's a bit of an egg on his face. There are reasons for Lou to stay away but some other reasons for him to consider the hire. If Lou extends an offer to MacLean, I could see him accepting, because he will want another NHL job and his tenure in Ottawa isn't so impressive that he's in a position to be too choosy.
Dan Bylsma: He coached the Penguins to a Cup way back in 2009 and the Penguins always made the playoffs under him (even if they had a ton of humiliating exits to lower seeds), but the fact that the Penguins might not make the playoffs and have looked pretty poor overall this year might make him not seem so terrible. He's known as an extreme player's coach and I'm not sure Lou would be a fan of that. Bylsma has great regular season and limited postseason success in the NHL and he would probably be popular in the locker room, so that might make him an attractive candidate to Lou. If Lou extends an offer to Bylsma, whether he accepts or not will probably depend on what other teams might be interested in his services (since after the Penguins falling apart this year, he might find his phone ringing more) or how much he enjoys being an analyst and just cashing checks for doing nothing from Pittsburg.
Todd McClellan: Assuming McClellan is handed his walking papers in San Jose, he will have guided the team to a great deal of regular season success and a mixed bag of playoff results (some series wins and some embarrassing series choked up). He's another Babcock protege, which again gives him a valuable education to draw on that Lou might appreciate. Based on his track record in San Jose, McClellan might get a fair number of phone calls this summer, or he might not. The number he gets might influence how likely he is to come here if Lou extends an offer.
Mike Babcock: I personally think he's the best coach in the NHL, so it would be like a pipe dream for me if he came here, but I don't believe it's likely. With the new owners, I think there would be the money to pay top dollar to draw a coach like him here, but other teams would certainly be throwing out similar offers and could probably offer more attractive situations to go to. Babcock is also rumored to want more control over player personnel, and I doubt that Lou would be willing to concede that even to entice Babcock to come here. It would be amazing if Babcock came here, but I just can't imagine it happening. It will be a very pleasant surprise if it does.
