1st, I do agree that we need an upgrade at TE.
But, 2nd, I don't see Higbee and Everett flip-flopping. They used Higbee as the in-line TE this year. I can't imagine them using Everett that way. Higbee is bigger and stronger than Everett, which is needed to be a decent in-line blocker. But to my mind, Higbee is a guy who really isn't a good enough blocker or receiver to be our starting TE. I'd love to find a little bigger TE who is a significantly better blocker and more reliable receiver, ideally with height so as to be a good Red Zone target.
