I don't know if this has already been posted on HH, but I thought it was definitely worth a post. This quite is from this article in the Washington Post (http://www.washingtonpost.com/blogs/dc-sports-bog/post/rgiii-responds-to-donovan-mcnabb/2012/04/19/gIQAVXabTT_blog.html)
“All respect to Donovan McNabb, he had a great career,” Griffin told Banks. “He was one of my dad’s [favorite] quarterbacks when he was a Philly fan. He’s not a Philly fan anymore, because I’m about to get drafted. But what [McNabb] said probably did come from a place of just bad taste. He had a bad taste in his mouth from his experience with Coach Shanahan, and I understand that. He never said anything bad about me, he was just trying to warn me, trying to say, ‘Don't let egos get in the way.’
“But that’s part of the job at quarterback, to be able to manage different types of egos and different types of people. So I’m looking forward to going up there and managing whatever it is that needs to be managed. All respect to Donovan, but it just didn’t work out for him in Washington, and that's why he thought it didn’t work out.”
Seems like he defends Shanahan a bit and tactfully says McNabb is just sucking on sour grabs and needs to move on.
