Liam Coen is an interesting name but I don't think we can take someone with zero HC experience.
I posted in another thread that I think Harasmyiak as HC and Coen as OC would be an interesting move as the former is defensive oriented and has previous HC experience at Maine. But now, looking at what Coen is making at Kentucky ($750K), I don't think he'd take a lateral move or take an HC job with an offer from an FBS indy for under $2 mill - and that's a lot for someone without of whiff of HC experience for UhConn at this time, given the state of the team and the finances.
Harasmyiak is due $410K in 2022 from Minnesota. UConn could triple his salary and go for a wunderkind like Scotty Walden at OC, and be well under $2 mill for both.
