Thats debatable. Depends on how you view the importance of the position and what needs to be done. Its obviously not how the coaching staff feels and neither do I.
A agree Wennberg is a black hole in creating chances, but his play up the middle does lead to more possession and reduces chances again. Thats a good thing. Its a much bigger issue defensively than offensively when talking about what you need from a center, in tight playoff games.
Sometimes keeping the other team even instead of scoring 3 and letting up 4 of 5 is the better route. I see what you are saying but I actually think thats a more balanced 200 ft line than going Cuylle Chytil Kakko. 3rd line will also likely be getting more minutes even strength.
I like that 4th line, I do - but not at the expense of Chytil JUST coming back in as a C the the conf finals. For the reasons i pointed out, probably the most important is managing Chytils skating/recovery/health and not giving him too many things to think about. We saw what it did to Mikas game trying to match up against Hughes last year. And I doubt Chytil would even be that concerned about things defensively, and thats part of the problem.
