I admit I don't get to watch of games out here on the West Coast but I do see lots of hi (low) lights. And it's very clear from my perch that Lehner is not a capable starter in the NHL. Backup, yes, but go to guy, no. Not by a long shot.
Yes he's tough and has a fire in his belly but that doesn't stop shyte goals like Martin's goal against Toronto. That is the goal that breaks a team's back. The one that deflates them.
The team also has too much dead weight. Too many slow, breaking down defencemen. I'd prefer the group get or use their best young D and let them get the experience. The team has 5 goals by defence this year. FIVE! 4 I believe are by #55 who is gonna be a beauty. The bottom 3 defence are old, slow and/or breaking down and that's not good. In Vancouver they have two young guys learning on the fly and they are not liabilities. Sure they make mistakes but they are dynamic players who are learning and will benefit from it. It's time for Buffalo to say goodbye to JG, who is a very nice guy but he isn't happy there and I know that from speaking with him. He didn't outright say it but his body language did and that's enough. Go with the younger kids and see what happens.
Offensively, I believe the team should open it up more and go for goals, as opposed to trying not to get scored on. They have offensive talent and it's time to let them go a bit more. Maybe it's time for a top coach not one who inherited Sid, Malkin and Co.
I know I'm rambling but something still isn't right there. But I'd start by looking for a true starter in net, or until then go with Nillson (although I didn't like the game winner)
