Question about the shelf life of Esports pros
I have been following Pro league really extensively this year and one thing that struck me as odd is the REALLY low expected career length of pro players. We are in season 5, so only 5 years have passed since it was a thing but still, there are less than a handful of players still around from the beginning and many casters and experts and such seem to think a players is a "old timer veteran" after like 2 or 3 splits.
Hell in physical sports even like NFL football the player career span average is much longer and that is in a sport where your body is constantly beat to hell and as you age you loss effectiveness. We still have players rountinely around 10+ years. Where as in LCS it seems that we have players in their early-mid twenties being considered to old to play and basically NO palyers over 30 or 35.
My question is, does this stem from some unseen reason I'm missing that causes them to not be able to compete or is it more that the rewards for being a professional esports players are not worth the effort long term. If it is the latter I think it would be super healthy to up the rewards and keep these players around, as they establish fan-bases and become icons in and of themselves, which fuels a ore popular scene all together
TL:DR can someone explain to me why pro players never play very long?
