I'm not sure how many people knew of its existence, but we've added a blog to this site now. Cap, just wrote up a good and brief breakdown of the Falcons cap situation.

From what he says, I do believe that Dunn will be retained. I'm just as sure Brady Smith won't be back. There may be a chance if he's unsigned after the draft and the Falcons can afford to bring him back at a 1-yr. minimum deal, but otherwise I don't see the Falcons giving him a contract extension (I believe he has just one year left on his contract) when they are poised to get a quality guy in the draft this year, plus they have Chauncey Davis as an option.
Weiner I'm not quite sure about. He could come back, but as Cappy mentioned, it may depend on if the team can work out a restructuring that saves nearly or the same amount of money it could by cutting him. I like Weiner a lot, but with the team poised to move on at LT, it may also be time to make the leap and move on at RT. Not to mention Barry Stokes was adequate as a starter (again he wouldn't be my ideal choice), so the team could save by re-signing him, and hoping they find a quality OT in the draft.
But it's nice to know that the Falcons aren't going to have to do a lot with restructuring to get under teh cap with Hall and Vick's bonuses. I think Kerney is going to get an extension, and I suspect the Falcons will find some way to save some cash on Brooking's contract.
