It’s almost done. It’s not yet done, but it’s almost done.

Jenny Vrentas and Dave Hutchinson of the Newark Star-Ledger report that the Jets and center Nick Mangold have agreed to terms on a seven-year, $55 million deal.

But while we’ve confirmed that the basic parameters have been satisfied as to duration and total dollars, we’re told that the deal is not yet done. The primary remaining issue? Guaranteed money.

Until there’s an agreement on this fairly important term, the deal isn’t and won’t be done. We’re nevertheless told that both sides hope to finalize the agreement after practice on Tuesday.
