What define a Player as a FREE AGENT for LCS?

Former Pros?

Challenger?

Attended NASG?

Or whoever Riot decide is Free Agent?

I see a few Players good enough or better than the current Pro, even the Over Rated Aphromoo

but they're not even consider Free Agent, how does this even work?

Cus this Esports thing isn't like College, where you have players to draft from to go into the big League.

And that's why they created NASG, but I find it really dumb to do it cus Team like TSM don't even need NASG to find better players. The only player to make it from NASG is OmarGod who is playing for CLG now as a starter since Dardoch got kick out (no surprise, he always get kick out LOL)
