He's one of my biggest dislikes of the entire draft class.
Dude is an exact size-speed match to Cole Beasley, but plays like he's Dez Bryant. It makes for fun tape to watch, but I don't think it's translatable.
If you are going to run that kind of Beasley, Edelman type game where you win on short slot routes all day, your timing needs to be sharp. Break and hit your spot in 2 seconds. And for the hundreds of passes Downs caught at UNC, not a lot of them were timing routes. He just kind of street-balled until he got open, and that won't play against much better athletes.
He is more than quick enough to play a timing based game. But that introduces a little risk to his profile compared to a dude like Addison, whose tape is nothing but crispy timing routes. Addison falls into that "zero chance he sucks" zone. Downs is more like "minimal chance he'll be elite, moderate chance he sucks", and I don't really like that for a 2nd rounder.
