Jay's lack of HC experience is a legit concern. However, it's entirely unfair to consider him Albie 2.0 just because he comes in with no HC experience and as our former associate HC.
It was clear the team excelled when Jay reportedly took on more player development responsibility this season after Christmas break. His resume coming into this job is very different from Albie's. IJay spent numerous years specifically in player development at multiple levels with the Bruins. Albie cut his chops mainly as a talent evaluator and recruiter. For the head coaching position, it's more important to have the former skill than the latter. Talent evaluation and recruiting can be handled mostly by associate/assistant HCs. This is where Jay would need to make a very strong hire - to me, Joe Pereira would be a slam dunk backfill as associate HC and the perfect complement.
The other big difference between Jay and Albie - one hung a banner at BU and has his name on the Cup twice, then came within one game of doing it again as a coach. Winners win wherever they go. For all of Albie's recruiting success, he never won anything anywhere at any level.
Re: Hastings - with Michigan State reportedly set to hire the USNTDP coach, I find it hard to believe he was a legitimate candidate anywhere. MSU had zero reason to pass on him if he was interested. My guess is both them and BU might've had some exploratory discussions, but nothing further and may not have even had a formal interview.
As far as I know, Jay is the only person who had a formal interview with President Brown at BU. In 2018, both Albie and Rick Bennett did.
