NHL career lengths

I was really hoping that this whole post was going to be irrelevant, since it started out of a discussion about how much money the typical NHL player makes over the course of career - as in, why do we care whether these millionaires get 53% of revenue or 50% of revenue - and it was my gut feeling that the typical NHL career looks a lot closer to Biz than to Ovie. TRAGICALLY, it's still relevant :((

Salary data proved to be too much, but what I was able to put together is a bunch of data around the length of NHL careers.
