How many hours does an LCS player spend in LOL per year?

I was thinking about something I read on basketball elite players and how their bodies call it quits after about 650-700 hours played. I'm thinking if you do LOL 2 hours a night, you can hit that number in a year. This gets me to thinking, maybe LCS players have such a short career because they are spending too much time each year with ranked, promotional stuff for the sponsers, and LCS games and there's only so much wear and tear a person's hands can take along with the other pressures.

Does anyone have any hard numbers on this?

I know you all have Lyte who's a psychological doctor on hand, but has anyone considered bringing in an ergonomic specialist or hand doctor to study this sort of thing?
