Many of those guys cannot or will not speak standard English.
Yet 95% will have to go out and get real jobs in the real world
where poor language skills will severely penalize them.
Colorado HC Deion Sanders, a supposed college graduate (I think),
chooses to use Black vernacular rather than speak using standard
English with the media. The message that Sanders is sending to his players
is that developing and presenting themselves as student-athletes means
NOTHING more than "acting White", which is for chumps.
