Now you're just talking about PR. If Manning actually made those comments, I'm confident he's talking about the last 10 years of Dan Snyder's football decision-making, not whether or not he makes an ass of himself in front of a microphone or TV camera.
Snyder may have learned some lessons from his mistakes - he deserves the chance to do so, and credit if he demonstrates that's a reality. But the truth is, he's been a disaster of an NFL owner for 20 years, and an aggressive, arrogant, self-serving disaster at that. And we can't fault any NFL star for being wary of that well-deserved reputation.
Sorry - but I think you'd have a hard time arguing otherwise.
