While I agree with a lot of what you wrote Panzer, injuries happen in the NHL, and I don't think having more grit will change that. Boston is missing players, Hughes got hurt (also got hurt last season), Hischier is out as well for the Devs, McDavid missed time. The list is long. The reality the Rangers have lived in the past few seasons of very few impactful injuries was very lucky, and we didn't have extra grit the past few seasons, yet we stayed mostly injury free. With that said, I agree with your point of needing more grit in general, so we are aligned, I just don't think overall I would correlate injuries with not having that grit.
And I totally agree about Laf and Kakko (good description of Kakko). This is their 3rd coach now, and I still see the same stuff. I cannot keep blaming others for these guys not stepping up. At least Laf has shown some life and scored some goals, and I still think there is something there for him, Kakko I have no words for anymore. I really hate to say this, but he is pretty useless IMO. I just don't see him adding much. He can control the puck sometimes using his body well to shield off players, but if nothing comes from it does it really matter - to me the answer is no it doesn't. Not sure what to do other than continuing to give them top 6 minutes and hope it clicks. It is the Rangers only chance to win big, barring a trade, so I think you have to.
Team is facing adversity now without Fox and Chytil, in a league where depth is at a premium due to the hard cap. We'll see if they can hold down the fort. At least they have winnable games at home coming up as I wrote above.
