Maybe because it's been such a long day, my mind came up with this:
The Jets received a fourth-rounder in 2008 for Vilma. If Vilma doesn't sign an extension with the Saints during or after the 2008 season, he becomes a free agent. The Jets could, conceivably, sign him back at no draft-pick cost.
Whew, it's getting late. And, to paraphrase Neil Best, I still have to go write a story for the actual newspaper on all of this. You remember the actual newspaper, right?
