Sport products evolves around Social Identity(fan identifying themselves with the team like wearing the team shirt), Emotions (fans n athletes), respect and loyalty to Coaches/Managers who brought the team higher (history).
So don't go changing the identity-color, badge/branding/crest and don't fire the beloved Coach/Manager
In the case of coach, we had something similar before-> Misbun Sidek who was Badminton world #1-Lee Chong Wei's coach - BAM (badminton association Malaysia) sideline Misbun...it was a big HooHaa
Another case was Diving Coach Yang Zhuliang who brought up Olympian Bryan Nickson and Pandelela Rinong,
In sports, legends (athlete, coach, manager) have loyal fans and no matter how business or economy it is to fire them or managerial revamp to the organisation, it is not wise to take away the identity nor contributors, history setters are the STARS and really appreciated. Color, symbols are sort of branding that is an established marketing for fans/clients/sport product consumers.
