Why the hype?
Assuming health, he can get separation like no one else in this class, he is a guy defenses will have to account for every snap, we can actually have a good returner again. Tons of room for improvement as well as while he is decent at routes, he can certainly get better there.
Also Perriman made plenty of spectacular catches but had quite a few drops in college. Think his drop rate was around 15%. And while Ross doesn't win jump balls a lot(wow, go figure with his size), the guy has had his share of really nice catches and his drop rate for last year was less than 5%.
Reasons why I would be concerned, health, not winning jump balls if your quarterback can't throw a deep ball where Ross doesn't have to wait everytime for the ball. Second one doesn't really apply to us although you could argue fit as we already have a ton of speed on the field. I'd just say Ross can win underneath with that quickness as CBs will be too scared of his speed. And if you give him extra attention, that opens things up for Wallace and Perriman.
Not my favorite pick at 16 but if healthy I would be fine with it and comparing him to Perriman based on 40 times is a disservice to both players.
