Again, if there was a serious medical issue (and I'm not talking about a hockey-related physical injury), Ranger management, coaching, training, and medical staff) would be aware of it and addressing it. Again...they see what we see. If you don't believe there has been some serious discussion between Ranger staff and MK then you are being short-sighted. His decline has been precipitous and obvious to all. Again, we have no idea, no clue, what is going on behind the scenes.
I'm still inclined to think that this is age-related. Faster than most, certainly, but well within the range of what is possible. Compounding this is a loss of confidence and an inability to adapt (as some players do with declining skills). No matter what you think of MK, this is sad to see. Age comes to all athletes. He might be only 31 but in my long life as a sports fan, that is not too early. Are not Met fans concerned with Pete Alonso's seeming decline (he won't be 30 until next month) and how he will age in the coming seasons? It hurts to be on the sideline and observe this. We are more used to seeing a gradual decline. We just have to wait and see what transpires.
