Well, Mangini will likely release him, to free up cap space, and, because they will pretty much get nothing for him if a trade occurs. Maybe a fourth or fifth round pick. That's like a baseball bat to me. The Jets are my second favorite team behind the Colts. I assume they wont keep him after aquiring Kris Jenkins from Carolina in a steal of a trade. They gave up a three and a five.
Unless a team is in love with Robertson, they won't trade him. He was drafted in the first round in the '05 draft. If they keep him, they would put him as a backup for Jenkins because Mangini plays a 3-4. They took a crack at Alan Faneca in free agency making him the highest paid G in the NFL. So cap space would be nice.
