As well as his ability to shield his body from a defender and adjust to the football while it's in flight.
In all honesty though, this team needs an over the top of the defense WR right now. We already have Kupp, Spruce and a quick, precise route runner in Woods. Reynolds is really the only legit deep speed threat. I don't count TA because he's quicker then fast and is short to boot. McRoberts will be fighting for that 6th spot. Hopefully, he's great on ST's.
