Signability: If a player is not drafted by age of 20, that player becomes an unrestricted free agent. A player not signed by drafted team within two years can reenter draft, assuming they are still eligible, and if they are not eligible, will become unrestricted an free agent. A team has the rights of an NCAA player until 30 days after the player leaves the college. If a player is drafted a second time, they can not reenter the draft. If a player has entered the draft twice and not been selected, they then become free agents regardless of age. A non-North American player can not be signed unless they are drafted first.
