The North American League recruited college, ex-major and ex-minor league players. Former affiliated-league players that get injured or have other circumstances would also join the NAL as an opportunity to get resigned by major league organizations. Other players consisted of college players that were not drafted into MiLB, but seek the opportunity to be seen by major league scouts and possibly get signed by major league organizations.
