Its not so much ignoring longevity... just not quite giving as much credit for it as some do, especially since those extra seasons of CC weren't really close to his peak talents, just slightly above average. On the other hand, when a guy can reinvent himself with worse stuff in order to pitch later on in this career, it's no reason to argue against him either.
I guess it just sucks to not see Felix go in, who I think is the better pitcher.
