Davis may never be an all-pro TE or even a number 1 tight end, but for what he is, he does a decent enough job. I have no idea why people watch someone struggle a bit as he learns a new system, then want to replace him with another average joe who'd have to start the learning process from the beginning again. We got a good upgrade at TE just by getting Miller back. Right now, I'm more concerned with Tate's injury and when Harvin will get back, and when we will (if ever) get back to full strength along that OLine. These are far more pressing IMO than our 3rd TE.
