I thought Fowler and Manson had several games where they looked good together at the beginning of this season. I also thought that last year that they were just as good as Lindholm/Manson. Now I will say that I think Fowler has struggled a bit this season, especially since his last injury. Seems more tentative than normal.
I 100% agree about Beauchemon/Montour being the ideal 3rd pairing. I'm on board with bringing in a defenseman to play with Fowler. I'm not trying to say that Manson/Fowler has to be a thing. I'm saying that with our current defense, I think our best, current top 4 combination is Fowler/Manson; Lindholm/Montour. I'd be fine if we brought in another D to play with Cam, as I think Lindholm/Manson is arguably our best pair. I just that think that with the current D, it's better to put Josh with Cam and Montour with Hampus because Fowler plays better when paired with a more stay at home guy like Josh.
