This is silly. The media is the medium for Kyler to tell his story. The media isn't attacking him.
These guys are all ex players and current coaches. Kyler disregarding his responsibilty to represent himself and the Cardinals through the media allows stories like this to become fact.
What other player in the league, especially a Quarterback, would allow "He doesn't study" to become an established narrative without correcting the record? Even if it's true you lie, you don't allow your reputation to become "He's the QB that doesn't study and just plays COD". He's let himself become a laughing stock. A meme.
This is only one example. I've seen 50 more similar to this clip below in the past 7 months. Yet not once has Kyler spoken out about it. He could easily go on a dozen NFL shows and easily correct this as part of a wider interview. It's gross negligence for him to allow this story to fester.
