Okay so the NFL Player's Association has the rights to all the player's names. I want to make an app using that uses Player's names. Take Brian Urlacher. Since I can't use his name as it is due to the NFLPA, is it okay to use it if it is changed by dropping a letter or vowel from his name? For example, could I legally use B. Urlcher or B. Ulacher? Thanks for the feedback.
