And again, if that broad jump was 10'7" instead of 9'7", his numbers are right on par with those other 3 guys.
Jump number don't get the media play that 40 times do, so people aren't as good at putting them into context. The difference between jumping 11'0" and 9'7" is like the difference between running a 4.35 and a 4.60. It's not something that should be casually brushed off. The 11'0" broad jump by Rogers and the 11'4" by Hunter are ELITE marks. The 9'7" by Hopkins is really quite poor for a 6'1" receiver. And the 4.57 40 time, while not completely horrible, was on the low end of the spectrum. Here are the 210+ pound receivers who ran at the combine and their corresponding 40 times

atterson - 216 - 4.42
Harrison - 231 - 4.46
R Smith - 225 - 4.51
Rogers - 217 - 4.52
Mellette - 217 - 4.54
Harper - 229 - 4.55
Davis - 233 - 4.56
Hamilton - 212 - 4.56
Hopkins - 214 - 4.57
Kaufman - 216 - 4.67
Hopkins is within a few hundredths of almost all of these guys, but nevertheless comes in near the bottom.
Here are the broad jump results for all of the 6'0"+ receivers who jumped at the combined. I excluded the short receivers because the results in this drill tend to reflect stride length and thus favor taller players, making it futile to compare the results of a 6'3" receiver with a smurf like Ace Sanders or Tavon Austin (who both outjumped Hopkins, btw).
Hunter - 6'4" - 11'4"
Rogers - 6'2.7" - 11'0"
Harrison - 6'2.7" - 10'9"
Stills - 6'0.4" - 10'4"
Mellette - 6'2.4" - 10'3"
Goard - 6'3.6" - 10'3"
Wilson - 6'2.5" - 10'2"
Fuller - 6'2" - 10'0"
Davis - 6'2.4" - 10'0"
R Smith - 6'4.3" - 10'0"
Williams - 6'2" - 9'11"
Patton - 6'0" - 9'10"
Woods - 6'0.3" - 9'9"
Harper - 6'0.6" - 9'8"
Hopkins - 6'1" - 9'7"
Kaufman - 6'5" - 9'7"
Lemon - 6'1.2" - 9'4"
Hamilton - 6'1.6" - 8'11"
This not only demonstrates just how elite Rogers and Hunter tested in this drill, but also how poorly Hopkins did.
I'm generally willing to overlook bad results in one drill, but when you get consistently low figures it starts to become a concern. The fact that Hopkins was near the back of the pack in the 40 and the broad jump tells me he probably doesn't have a great deal of upfield explosiveness. He has a good frame and the solid vertical leap suggests a little bit of lower body power/fast twitch quickness, but overall his profile leaves a lot to be desired. Hence why I peg him as a second tier player. He likely doesn't have the pure juice to become a dominant pro #1.
For the sake of comparison, here is what some of the top NFL receivers did at the combine/pro day. The first figure is the BMI. The next three numbers are the 40 time, vertical, and broad jump:
Andre Johnson - 29.5 (4.41 - 39" - 11'0")
Vincent Jackson - 28.9 (4.46 - 39" - 10'9")
Dez Bryant - 28.8 (4.52 - 38" - 11'1")
Victor Cruz - 28.3 (4.47 - 41.5" - 10'5")
Calvin Johnson - 28.3 (4.35 - 42.5" - 11'7")
Larry Fitzgerald - 28.3 - results not available
Hakeem Nicks - 28.3 (4.51, 36", ??)
Michael Crabtree - 28.1 - did not work out before the draft
Demaryius Thomas - did not work out before the draft
Julio Jones - 27.8 (4.34 - 38.5" - 11'3")
Brandon Marshall - 27.6 (4.52 - 37" - 10'0")
Roddy White - 27.2 (4.46 - 41" - 10'6")
Steve Smith - 27.2 (4.41 - 38.5" - 10'1")
Reggie Wayne - 26.9 (4.45 - 36" - ???)
Marques Colston - 26.9 (4.50 - 37" - 10'3")
Percy Harvin - 26.7 (4.39 - 37.5" - 10'1")
AJ Green - 26.0 (4.48 - 34.5" - 10'6")
What this list tells me:
- Elite workout numbers are not sufficient in order to become an elite pro WR, but almost all elite NFL WRs were standout performers.
- You'll note that every single WR on this list ran below 4.55 and jumped at least 34.5" in the vert and 10'0" in the broad jump.
- 13 of the 14 WRs tested in the vertical jump matched or exceeded the 36" mark set by Hopkins.
- 14 of 14 WRs had a faster 40 time than Hopkins.
- 12 of 12 WRs had a longer broad jump than Hopkins.
So I think it's more than fair to say that he has questionable athleticism for a #1 WR. He's a dominant athlete compared to the average joe on the street, and he's a decent athlete compared to the average top WR prospect in his draft class, but he is totally outclassed by the vast majority of top flight NFL receivers. You could say he's within touching distance of Nicks, Colston, and Marshall from a measurables standpoint. That's probably a stretch though and he's nowhere near the Julio/Andre/Dez/Calvin/VJax level.
Contrast that with some of his classmates:
Marcus Davis - 29.0 (4.56 - 39.5" - 10'0")
Mark Harrison - 28.8 (4.46 - 38.5" - 10'9")
Josh Boyce - 28.6 (4.38 - 34" - 10'11")
Cordarrelle Patterson - 27.7 (4.42 - 37" - 10'8")
Da'Rick Rogers - 27.7 (4.52 - 39.5" - 11")
Ryan Swope - 27.5 (4.34 - 37" - 10'5")
Marquise Goodwin - 27.3 (4.27 - ? - 11'0")
Markus Wheaton - 26.3 (4.45 - 37" - 10'0")
Justin Hunter - 24.6 (4.44 - 39.5" - 11'4")
Many of these players have significant warts of their own and I'm not high on all of them, but this is probably a pretty good starting point if you're looking for a receiver from this draft class who has a chance to become a standout pro independent of supporting cast. When we look back at this class a few years from now, my guess is that the best players from this group will be names from the above list. Players like Woods, Patton, and Hopkins might be solid complementary guys, but on the surface don't seem to have strong WR1 potential.
