Boston is an older team and I have a lot of questions about their team going into next season. I don't think their middle 6 forward group is particularly strong--they have some good players--Krejci (if he can stay healthy), Debrusk and Coyle but other than that I don't know. Kase does not do a whole lot for me. Other things are who is going to replace Krug to run their powerplay from the blue line. McAvoy no doubt will get some of that. McAvoy is just an all around better player than Krug but Krug's offensive instincts are superior to McAvoy's IMO. Does Chara come back?--if he doesn't that's a leadership hole--and what about Rask?---will he play in a bubble if that's how the season begins? are the Bruins going to move on from him anyway? Losing Chara and Krug would be losing two very established vets in front of him. They're absolutely going to need to have guys take a step up this year. They're hoping Studnicka will be one of them but they're not really deep in prospects.
I can see the Bruins easily falling back this year. That could happen to the Pens, the Caps and the Islanders as well.
