Says it was edited January 31, the day before the Super Bowl. I remember seeing the piece pretty early on, before the press conferences.
He put out another piece before the Super Bowl:
"So go Patriots. Crush the Seahawks with firm balls all above 12.5 PSI. Win big. I am cheering for you 112.5% percent.
But after the fact, if it turns out you did cheat in the AFC Championship game? Well, I will feel angry and guilty and you should be punished. That makes sense. And I do too. Probably."

Guy seems to have genuinely followed the team since the dark days and wrote a knee jerk op ed in the national spotlight. Judge him as necessary.
