I don't know how many of these guys will actually hit the open market and who knows how much the Jers will have to spend, but there are some good players available.
Tarvaris Jackson would be a decent, cheap option to come compete with Sanchez.
They really need a TE. Missed out on Martellus bennett last year, maybe they get him this year. Jared Cook is another guy to look at.
At WR, I like Edwards, Louis Murphy and Hartline.
There should be plenty of OL to choose from.
