Team needs (After Trading Up)

We've traded all of our high picks for this year, and we're sure to have our quarterback of the future (and present?). However with Tavon Austin as our WR1, we have some holes in our team that cannot be filled immediately with 6th round picks.

Needs: WR, TE, C, SS

We still lack a go-to receiver to carry us to some wins. We let go of Jared Cook with no replacement. Barnes is still our Center, who could be a decent placeholder, but is no way a long term option. And lastly, we still need McLeods replacement. Even if we were to put a corner there, we would still need depth.

There's a few more free agents out there. Who would you like to see signed?
