Lanyards Required/Elimination of Coaches Cards. This Fall 2018 BAYS phased out and eliminated the small BAYS coach ID card. The Mass Youth Soccer adult credential (aka "the lanyard") is required to be worn by all team officials on the team sideline (Max of 3). NOTE that this does not affect tournament play. Coaches should contact the administration of any tournament they expect to play in to confirm their requirements for coach credentials.
