No, I don't want him to coach the Oilers. It was a prediction, not a wish.
Sorry I missed the sarcasm nuance you intended! Coaches are as amazing as the talent they can put on the ice or not. Chronic bad franchises cycle through pinning their change on one variable, the coaching change. Edmonton and Buffalo are two most recent examples of bad organizations that have reactive, turnstile blame the coach mentality which doesn't change the bigger picture of poor team construction and mediocre talent. Tippett's brought a calming effect to a disparate collection of individuals which are finally molding into a team, nurturing a strong and confident leadership core which has been an issue forever (homegrown vs. buy and import it), all of the production measures are up for this team and substantively from its starting point of a bottom ten loser. The lone chronic issue is 5x5 scoring which reinforces the lack of depth on this team and primary focus to move this team forward now as a repeat playoff team in two years. Hard lesson losing a coin flip series to a reset Vezina winner, taking away McDavid's track meet attack game, and winning OT games with better quality players like Connors, Ehlers, and Stastny.
There's just no magic bullet as a coaching solution.
EDIT: I think one clear eyed take-away from the exit interviews is Tippett's own where he said he's not interested in an extension (despite the significant improvements made). He's clear eyed on this three year commitment to build a winning culture and prepare it to compete and win in playoff style tight checking games. Tippett's a pretty self-aware guy.
