2017 Recruiting I believe that there is three different times a walk on can be added in the FCS. The three times are the start of fall camp, the beginning of the academic year and spring practice. I believe fall camp in the FCS is limited to 95 players and this is the time most preferred walk on are added. When school starts the team can be expanded to 105 players and you will see players added then. They also add players in the Spring of their freshmen year and these are players that were not promised a spot on the team, but are more or less trying out for the team.
