Who's Bylsma? Bylsma inherited a Cup Finalist. Sullivan inherited a mess and immediately won two Cups.
Things are falling apart? News to me.
The myth that Sullivan inherited a mess has always been comical. JR traded Scuderi for Daley, took a risk on Schultz, and Perron for Hagelin that first cup run. He then brought up some youth from WBS in some limited roles, others to inject some speed and youth in the line-up and others played a bigger role - Guentzel, Rust, Kuhnhackl, Murray (went god mode in WBS and earned a call up in December of 2015). Imagine calling a team a mess that still had Sid, Geno, Kessel, Horny, Kunitz (still a 40pt player then)...vs using Talbot in the top 6 in the playoffs or Fedotenko as a top 6 winger.
The team was 15-10-1 when MJ was fired, he was painful to watch coach this team, but this wasn't a team that was 27-25-0-2 and spiraling out of contention
I mean, you want to talk about a mess? Go look at the team that was iced from 2005-2009. Jordan Staal was what, virtually in tears with Therrien as a coach and was thankful for Bylsma? We hate Bylsma now, but like Sullivan, he brought some good with him when he first got there, what Bylsma did with some awful rosters can't be taken for granted just because you can now bitch and whine about it to make Sully look better when Sully has literally trended the same way, with a better roster, especially in the playoffs the last 4yrs.
And let me be super clear - I don't like Bylsma, MJ, or Sully. I think all three are shit. DB and MS are both veteran friendly coaches and show as much. The notion they both liked youth died within the first 3yrs of their careers.
