Yeah, they're just ideas with varying degrees of realism or risk. But hey, if I'm going to say "these are problems," I may as well offer possible solutions.
With Ducharme, there's always the chance his stock plummets if Canada flops in the WJC medal round. I see a lot of people blaming him for not playing Makar more at WJC and blaming him for taking Comtois (whose dirty hit changed the game yesterday) over guys like Glass and Tippett. I agree it's a long shot, but it's worth a shot, right?
Do agree HS coaches won't cut it in HE, I was largely spitballing guys who have a past with UVM, plus Rolston and Ellsworth whose names came up a lot this summer. Maybe Ryan Papaioannou from Brooks in the AJHL? We've taken how many recruits from there, why not add the coach too lol
WRT Quinn's BU assistants, I'm unsure. Yeah they can recruit, but BU gets caught up in playing pond hockey a lot  where they try to just out-skill the other team. That might be more on Quinn though.
