Late to the "party" here, which provides a different context than earlier posters, but I'll say now what I would have said before the Jets looked like garbage two games in a row.
I've been impressed with Chevy overall - I believe he's learned from the Stuart, Thorburn & Pavelec contracts. I think the Kane fiasco helped reinforce their 'good character' approach to drafting. Every GM will make some mistakes, but I think he's made fewer over time and I'm very impressed with our Jets & Moose roster.
I'm cautiously optimistic about Maurice. I really liked him the first 2 years and was impressed with his press conferences. Then I started wondering if he was ALL talk when he was saying unbelievable things (like the "it's not rec hockey" comment, but then turning around and rewarding players that sucked but looked like they're trying hard, or throwing rookies/young guys under the bus when it was the vets taking most of the undisciplined penalties).
The results this year and Wheeler's comments have helped assuage some of my skepticism, but I still believe there is a lot of room to improve in the coaching department. My current theory is that some of the past questionable personnel decisions may have been influenced by assistant coaches (like Huddy on D in particular - I recall Mo saying he wasn't an expert re: defense a few years ago and deferred to Huddy, something like that anyway).
PP is mostly improved with room to get even better, but our PK is only good because of goaltending - Hellebuyck has been able to track extremely well and has covered up an abysmal system in my opinion.
So my conclusion - Chevy deserved an extension; Mo didn't from a performance standpoint, but I'm fine with him staying if we can get a couple of better assistants. I think he is a great speaker, inspirer and figurehead, but he needs better people to help with in-game adjustments, line deployments and PK systems.
His talents are valuable and helpful, but no one is good at everything.
