Per Rotoworld, the team wanted Mangold to take a pay cut.
The Jets have also cleared million with left tackle Ryan Clady and another .5 million with right tackle Breno Giacomini off the roster.
Host Bob Papa tossed out the Patriots as a good-natured hypothetical, knowing the bitter rivalry; there has been no Mangold-Patriots speculation. Belichick signed Darrelle Revis in 2014 and won a Super Bowl with him.
Mangold, cut by the Jets in February, said he's still having physical therapy on his injured foot. He said it has been "a slow grind since the end of the season," admitting the rehab has been "a little difficult for me."Mangold still hopes to play for a 12th season.
This follows the Giants’ 2016 offseason signing of defensive tackle Damon “Snacks” Harrison, another ex-Jet.
"I'm just rehabbing, trying to get right, trying to get ready," Mangold told Newsday.
"We're still trying to see what the options are," Mangold told Newsday when asked about retirement.
Willie Colon, Mangold’s retired former teammate, first floated that there are “rumbles” of Giants interest in Mangold on ESPN radio in mid-March.
The Daily News now can confirm the organization’s interest in the seven-time Pro Bowler and two-time All-Pro who would bring leadership, nastiness and hunger to the line.
