Newsflash: Just about nobody writes their own quotes in press releases.
I have written press releases before in my career and, like most people handling any PR duties, you write the quotes for the person in your organization who is being "quoted," they review them, make changes maybe, and approve. Or, alternatively, you get them to write the quotes, you clean them up (which is done for corporate CEOs who have ****** spelling and punctuation, not just learning disabled football players), then have the cleaned-up version approved for release.
Unless you're someone specific about writing your own quotes, this is how it works. To pretend everyone's caught Powe defrauding the public is just plain silly.
Whoever posted something about how he should now give press conferences to prove he is so eloquent -- yeah, no crap that a football player might not be eloquent. Again, press releases are edited and honed by PR people.
