I'm not sure about that. Being of current Jewish religious faith, I know that there are more then one names of G-d that we cannot say. The worst is pronouncing any transliteration of the word YHWH even during prayer. The word Sha-dai is also very harsh and is usually replaced with the word Shakai when not praying. Words like E-l, Elo-heinu, and most notably Ado-nai are not supposed to be pronounced while referring to G-d. However, while not referring to G-d and referring to a football player in this case, one should be very careful saying it but it might be okay. To be safe though, I recommend just call him "AD" because he goes by that anyways.
