As to the question of which schools’ jerseys would be safe for the Nayv-adorned kicker, here’s the best I — with some help — could do for D-1 schools:

UMass
Bucknell
Southern Miss
Ole Miss

Other schools have Nayv-safe names, but they do not display that name on their jerseys.  These schools include:

Tennessee (no text)
UConn (jerseys say Connecticut)
Marshall (jerseys say Herd)
Hawaii (jerseys say Warriors)
Cornell (no text)
Gardner-Webb (jerseys say Dogs)
