I'm sure I'm not the only one, but having watched Chris struggle physically the last year, and not look particularly mobile or dynamic this preseason, I can't say it's a shock they'd let him go. We just don't have the luxury of keeping guys like that--veteran, expensive--on the roster. Not while trying to build a fast, dynamic young team for RG3.
That they let him go NOW says to me it's so he has a chance to catch on elsewhere. If they'd waited until final cuts, it would be much harder for him to find a home. I'd like to think the team is being classy in that regard.
And on a purely practical note....if there is cap space freed up for possible use shoring up the OL, that's not something to turn a blind eye to either. Haven't done the math on that though, so it may be wishful thinking.
Have to separate the emotional attachment for a player who has, in the past, been a favorite. Cooley hasn't been Cooley on the field for a while, and I can't say I had or have any real hopes that he will be Cooley again elsewhere. I hope so though. As long as it's outside the NFCE.
