i'm fairly certain that the deal has been in place for at least a year that BM stays on through the drafts and probably at least partially into the next season to protect Eakins continuing as head coach to start next season. Eakins will probably be the only protected coaching position going into next season, the rest of the coaching staff (including training and medical) i think will be shopped and replaced, but it'll be difficult because whoever comes in will know that they'll likely get the boot if/when Eakins gets kicked by a new GM.
some of the timing on when people step down or get fired will probably be dependent upon how the team performs to start next season. i doubt injuries will be allowed to excuse poor performance - it'll be: make it work, prove you're up to the challenge, or we get someone else.
BM will step down before half the season is over, UNLESS the team goes on some kind of miraculous winning streak to start the season - it'd have to be a franchise record, though. regardless, BM will step down as GM next season, probably as part of a deal to bring in someone new. any interim GM will be home grown, but i doubt they hire a new non-interim GM from within. it wouldn't be shocking for them to promote from within, but it'd be disappointing, and my personal opinion is that it would extend all our problems with team performance, league view of the team, etc. it would be an ownership failure, even if it were part of a long view strategy - it's just too conservative an approach for a rebuilding team.
i think BM will do whatever he can to give Eakins one last fair shot at HC. regardless of the majority opinion voiced on this forum, you'd be hard pressed to find any executive in the league that thinks Eakins has been given a fair shot to date, not with this set of players, and not under the various extenuating circumstances. some of the blame Eakins gets saddled with, regardless, because he accepted the job knowing how things would go down, but, for me, it's just too harsh to judge his coaching prowess based on what's happened in the past two seasons. i admit Eakins hasn't done much to impress me through this season (I purposefully withheld judgement until the season was over), but I'm not sure the plan has been to build a team that needs a herculean coaching effort to beat the teams that were in our division this season. that said, i've liked the development of a few players over the season... it was slow, but it seems pretty solid/reliable. and, the ones that haven't developed (or floundered) are pretty apparent. there's value in that.
at this point, it stretches credibility to think that there's some viable master plan that'll bring all these possible machinations together into a solidly rebuilt team... but i'm not willing to overlook all the mountains of extenuating circumstances to Eakins detriment, and i still think there's potential for an upside to him being HC to start next season. BM has all but announced his retirement from the Ducks, so i'm not super concerned with his future, and i think he's just too conservative an operator to handicap the Ducks with too little flexibility going forward.
man, we could write a really interesting book comparing and contrasting the ~recent GM switch in Toronto with how the GM switch is going to happen in Anaheim. lots of interpersonal similarities, lots of stark strategic differences.
