Winston needs people with deep speed that can run deep routes. His best skill is the deep ball off of play action. Right now all we really have as far as a deep threat is Harty who is fast as hell, but he's also 5'6" and 170 lbs. That's a tough target to hit and at 170 lbs. he's prone to getting hurt.
I like that they're interested in a big body guy with deep speed. Makes me think guys like J Williams, C Watson or A Pierce will be heavily considered in the draft
