If teams knew how to measure the aging process scientifically, they could save a ton of money. But they don't. How do we differentiate between a Crosby, still effective well into his thirties, and a Zibanejad, a ghost of himself at 31? You can't. It's not effort or dedication. It's science. In my 60+ years as a hockey fan, I must admit this has been about the most abrupt falloff I have seen. Not unprecedented but as bad as I've seen. But there were signs, even last year. I'm sure the Rangers have put him through all sorts of medical tests and unless they are keeping something serious hidden from us, what we have is simply a player aging prematurely. Studying the aging process and what is called "life extension" is an emerging field in scientific research. You can bet the Ranger medical staff is well-versed in the research. At some point, this is going to have to be addressed. He is hurting the team. This will get worse. But I do feel for the guy, who, at age 31, can't do what he once did. It's not like he is in a "normal" profession where 31 is young. It's a sorry state and a major albatross around this team's proverbial neck.
