How will chris samuels's retirement affect our cap?

Come March 5th, or once the cap is dead, there will be a flurry of retirements/cuts, Chris should be one of the retirees. He was/is awesome, and should go into the Redskins Ring as soon as possible, but our team needs to move forward now.

why would he come back? Neck injuries are no joke and he should take that seriously plus he has a fat check coming his way from re-negotiating his contract. He's had a great career and he'll be missed.

Redskins’ Chris Samuels to Decide Future in February (http://www.footballnewsnow.com/2009/redskins-chris-samuels-to-decide-future-in-february/)

this isnt the article i reaad, the one i read was much more in-depth about his re-evaluation in feb. but it hits the gist.

samuels retiring looks more likely than not, but there is still a chance he will come back. im torn. i really really want him to come back and if he and the doctors decide he can then im with it . .. but im scared as hell for him if he does.

Here is a good analysis of the upcoming uncapped year by J I Halsell, especially in regards to the expectation of a new CBA. He talks about the possibility of there being some charge against the 2011 cap (which he believes will be in the next CBA) for 2010 uncapped moves.
It is all speculation, but he certainly has the knowledge and background to make credible statements:
