Maybe Engram could step it up in our offense. But I think the Rams are already sitting on a guy who can help them in Harris. Everyone wants to make a big deal out of Harris' blocking but when you line a guy like him up outside he brings a defender with him. It is still elimination of the defender effectively for a run, and Higs can play inline. Basically Harris would have teams throwing out a personnel grouping to match with 11 sets, and could still line up off the edge and is big enough and willing to get his hands dirty that he could help us out.
So for me play Harris and trade for a safety who can pair with Fuller. That's what I'd do and I think the Rams are stronger than just trading for an underachieving TE who won't be in the plan longer than this season. And who will probably get supplanted by Harris sooner than later.
