He is a physical receiver with great hands and very good acceleration. A more dynamic Deebo Samuel, if you like what he's done so far.
Every Isaiah McKenzie run you saw this year would be a Shenault run in 2020. A guy with ability to take a quick slant or a WR screen to the house, while also possessing the speed to take the top off a defense.
At 6'2" 220lbs, running a 4.38 40, what isn't there to like? He's built for this team and this offense.
