QB Contract Extensions: Brady agrees to deal; Peyton next? McNabb??

[Ruhskins]

Well, it seems that Brady and the Pats have agreed to a deal:

New England Patriots, Tom Brady agree on a 4-year contract extension, according to source close to negotiation - ESPN Boston

I wonder if this will have any effect on Manning's talks with the Colts, and in turn how all of this could have an effect on McNabb's extension. It should be an interesting subplot in the early weeks of the new season (and I thought it would be a good thread to have).
