I'm a bit hesitant to call for Housley's head. The most important measure of a coach (to me) is whether the team under or over preforms it's talent level. Looking at our roster I would say 10th in the East is probably about right, or even a slight over-performance. We only have 3 forwards that would be better than 4th liners on most teams.
I'm thinking we'll see at least 1 more season with both Housley and Botterill. That could change if the team really gives up down the stretch...
His usage belies any sort of capability to get more out of what he has than he does. He regularly saturates a single line with his only established players, when he does separate them out and gets traction from a second line, it doesn't last. He clearly ignores his analytics people when it comes to not only his forwards but more importantly his d-pairings. His powerplay is inept, his penalty killing spotty and his handling of goaltenders is haphazard rather than planned. There is no nuance to the man as a coach and the results are not good.
And then there is the dillweed who hired him and has done nothing all season to fill obvious, even glaring needs.
