Which ancillary weapon benefits most from the revamped WRs?

The Tight Ends will benefit most, because they will look better than they really are with coverage focused elsewhere.

If Hill is used creatively then he could do a lot of damage, from runs, deep routes, and an occasional pass.

If they force the Trautman Project on us then it would be unfortunate - he would look artificially good when we should be focused on getting a Tight End that helps the rest of the offense rather than the other way around.
