You mean Marshall, Decker, and Kerley is a really good 3 WR. Harvin is gone (not worth $10.5M as well as a 4th round pick). And Kerley is a good slot receiver so it still fits.
Sounds good, but then what was the point in trading for Harvin in the first place?

The QB situation is easily resolved. Marcus Mariotta may be available at 6, and they could either go with him or trade with Philly for 2 Firsts and Foles.
That or Mark Sanchez and Matt Moore are available in Free Agency.
Ahhh... got to go with Matt Moore. He's not great, but he's solid and can get the job done with the right pieces, and it seems like the Jets have that atm (although I don't know how good their offensive line is).
