I don't think too many are saying he is as good as Green or Jones, just the best prospect since then. See the Cosell quote below.
"You can make the argument that he's the best wide receiver to come out since the A.J. Green/Julio Jones 2011 draft."
Possibly they are the best since Johnson, since if Watkins receives a top 5 grade (regardless of who thinks he shouldn't), and is drafted between top 5-10, that would be better than Demaryius Thomas and Dez Bryant, AS PROSPECTS. Similarly, Gordon went later, in the second round, and while very gifted, that partly reflected the risk he presented at the time, and still does.
Green is listed at 207 lbs. That would make him 3" taller and 2 lbs. heavier.
Watkins does some things better than Torrey Smith, which might be one reason teams didn't spend a top 5 pick on him, and he was never really in the discussion for that high a pick, unlike Watkins.
From the [Dynasty] 2014 Draft Prospects thread (page 52).
Xue (comparing Watkins and Lee)
"Watkins has better body control and catches away from his body better."
Xue (comparing with Lee again, also with Torrey Smith)
"It is known who has the better catch radius: Watkins. He catches the ball away from his body more often and has better body control. You don't need measurable to tell you this. Torrey Smith has a 41" vertical yet isn't exactly one of the best at jumpballs."
Xue (on alleged route running and COD shortcomings of Watkins relative to Lee)
"Simply watching them run routes. Certain receivers can run certain routes much better than others. Unless a guy is asked to run a lot of square routes or comebacks, I don't worry much about having great or crazy change of direction. Someone like Odell Beckham is the best at sharp-breaking routes and comebacks, but that doesn't mean he'll put up a crazy shuttle or 3-cone time.
Here is a route by Watkins with a double move:

A bit choppy, but his speed and athleticism out of his breaks will more than make up for any lack of ability to change direction that you think he has."
Time Kibitzer (also comparing Watkins and Lee)
"I don't think we need to see combine results to know Sammy Watkins has a better catch radius than Marqise Lee, imo it's pretty obvious just watching their highlights. Sammy Watkins high points the ball on every single pass he receives, allowing him to much more readily catch inaccurate passes and win jump balls, whereas Lee tries to body catch whenever possible. Even if Lee has an insane vertical and a go-go gadget-like arm length, it's not gonna make up for Watkins innate receiving skills in regard to catch radius imo.
Secondly, personally I don't know how you can watch Watkins and not see excellent acceleration, let alone not see good acceleration. Watch the sequence from 3:12-3:29
