Coates is faster, taller, and stronger than Cooper, I don't get that ranking, particularly from you Xue. Cooper is nice cause he's pretty safe I guess, but his upside is limited; he's not someone to spend a 1st round rookie pick on imo.
As for Dyer, one thing that isn't being mentioned is his utter lack of any receiving ability. Signs currently point to him never being a 3rd down back; so you gotta rely on him getting 10+ TDs on the ground a year for him to even contend to be an RB1 in fantasy. Then when you add in his age and character concerns, I don't see much reason for the hoopla. I get that he's dirt cheap, but his upside:risk ratio just isn't good enough for him to warrant a roster spot in anything but the very deep devy leagues imo. I'd agree in a 10 rounder he's worth a shot in the later rounds, though he wouldn't be the kind of player I'd personally be targetting.
They're different types of players, but it's close between these two. Yes Coates has more upside (can you quantify it though?), but I don't think Cooper is that limited. He ran a
4.44 on video. So I know his speed is at least legit. I had him pegged as a high 4.4x to 4.50 before I got a hold of the video. I'm not sure if he will put up a great vertical or broad jump. But his 3-cone and shuttle should be really good. His footwork and short area quickness/explosion are top notch. He's without a doubt the most "pro-ready" WR in this class. Look at these moves in
high school.
As far as being "bigger", Cooper is looking bigger himself these days:

His physique looks a lot like Davante Adams', which is who I compare him to. He's listed at 205, but could be pushing 210-215.
Another thing that might favor Cooper is that he's a year younger than Coates.
Coates is somewhere between Torrey Smith and Sammy Watkins. Cooper is in the mold of Michael Crabtree/Davante Adams/DeAndre Hopkins/Hakeem Nicks. I don't think you can go wrong with either player.
Being faster, taller, and stronger doesn't automatically make you a better prospect, especially if you're not similar and all things aren't equal. I mean Melvin Gordon should be better than Corey Clement right?
