If we improve the situation at TE and OL, we don't need an OBJ type WR. We need better than we got last year for sure, but with Gronk (and less than optimal Gronkness) and Dwayne Allen, with Develin and a solid OL, we outscored Mahomes IN Kansas City with a WR corp of Edelman, Dorsett, the ghost of Hogan, and Cordarelle Patterson.
Obviously if we were to draft a supremely talented WR (intentionally or through dumb luck), or happen to get a mid-range veteran or a really talented guy on a prove it deal (like the Moss trade), those make our offense better. But for the overall health of the team, TE/OL has to be the primary focus. In that scenario, I like the idea of upgrading Sanu with a few veterans in the same salary range, and letting them compete with Harry/Meyers for spots and roles. Again, only if the TE situation improves, which admittedly is no easy task. There's only so many dual threat, difference making TE's out there.
