In regards to a relationship, yes, Ryan is my younger brother.  He is not with the Jaguars, nor does he have a contract with them.  Only players with a signed contract can ever be considered roster players or members of the team/squad/franchise, where try-out players have no formal standing as a member of a team.  It is not uncommon for a free-agent player to 'try-out' or be 'worked-out' by multiple teams over a short period of time - none of which qualifies the player as a member of the franchise.  Perhaps for clarification analogies could be used: tryouts/workouts are equivalent to job interviews, pre-season would be equivalent to a three month internship, practice squad would be equivalent to a long-term paid apprenticeship (lasting up to two years), inactive roster players would be equivalent to full-time fully-licensed substitute teachers who are on the pay roll and have to report to work every day regardless if a staff-teacher (i.e. active roster player) is out or not. Practice players are considered part of the franchise, but not members of the team or squad as they are under a different arrangement than the actual team/squad players which are comprised of both active and inactive roster players.
