Sanders has spent his four year NFL career with the Steelers.
I think you have to take that to mean there is lukewarm interest from the Jets if they are postponing the visit. If a player is a priority, you make his visit the scheduling conflict to cancel others to cancelling other things.
I think the Jets need to add at least one more receiver and a tight end heading into the Draft. If the price is right, Sanders would be a decent option. He is fairly versatile. I also think there are other options out there who would work just as well for this team.
