The rams website has photos of the players in their sweatsuits boarding and sitting on the plane to go to ATL. You look at Cooper's picture, he is smiling, but there is straight sadness there.
I saw him in New Orleans and same thing. You could tell he was bummed and that is totally understandable. I mean other than Tom Brady, even the greatest players of all time with great longevity are lucky to get 3-4 cracks at this big dance.
Its a really big deal and a lost opportunity and he is smart enough to know it.
