Ohio State University made them stop wearing them, and reimbursed them the money they apparently paid a staffer for them.
A couple things:
-This loyalty is understandable, as Tressel (and his staff) recruited these players, sometimes for years
-These kids (hopefully) don't understand that wearing something like that pokes a finger into the eye of the university and NCAA in some sort of misguided show of support for a discredited coach who will never coach at a high level again
-But it's no big deal. It's not a huge poke in the eye--it's basically on the same level as Terrelle Pryor wearing eye black supporting Michael Vick. Distasteful maybe, unwise certainly, important not at all.
