Happy to find someone writing on how esports is evolving. I’m already a huge fan of Weldon, so it’s good to add you to my reading. Here are some thoughts on your predictions.
Wouldn’t we need to see more multi-year sponsorship contracts first before seeing salary caps? The big problem being that esports team’s don’t have predictable revenue, which brought about the recent changes from Riot? http://www.lolesports.com/en_US/articles/lol-esports-now-and-future
For boot strapped teams, I’d expect the barrier of entry to begin to rise out of the demand for better coaching and then continue through investments in the organization, so that players will end up joining not only for better pay but to work along side coaches and analysts that win, not just players.
Another prediction I might ask would be around the a rise in the average player age. The longer a single competitive game sticks around and the more main stream esports becomes, the longer players are able to remain relevant and support themselves with a salary. Additionally, as games continue to add developed with more depth veterans would be more rewarded. http://nexus.leagueoflegends.com/2016/10/dev-on-depth-vs-accessibility/
