Who's getting all the snaps? Did Parker have the majority of the snaps along with Stills? Are Amendola and Wilson splitting time? What about Grant, is he getting a lot more looks? It's a good thing that there's so many players to choose from but 10 plays for Wilson seems a bit light.
Well, Stills, Parker, and Amendola are the top three receivers. For reference, Stills got 40 of 44 offensive snaps, Parker 33 and Amendola 31. Finally, Jakeem Grant got 9 snaps on offense. (Just for kicks, the Dolphins had 44 offensive snaps that game, the Raiders 82!)
Parker seems to keep getting snaps because he's big. Teams value size to a disproportionate degree, IMHO. Not that I wouldn't mind a Gronk, but he is very much an outlier -- we do actually have 3 TE/WR types on the team at Gronk sized or bigger, but they aren't exactly lighting it up.
The knock on Wilson is that he's only 5'9", but if you look at his "next gen stats" on NFL.com, he scored the HIGHEST in average separation of anyone in the NFL (with 43+ targets) and he just missed out on most YAC per reception. Lots of things affect these stats that aren't under the control of the receiver, of course, but he has a very solid catch rate, creates separation, and gets huge YAC. What else do you want? (And, yes, before anyone else points it out, his numbers might be a bit inflated because he isn't seeing #1 CB coverage, but with that argument, where are all the other average receivers with great numbers?)
The problem on the Dolphins is probably that there are just a lot of quite good receivers. Jakeem Grant had 2 touchdowns against the Raiders and is averaging 15 yards a reception this season. That's going to keep him in the rotation. Grant didn't see much action his first two seasons and, again, I think height (5'7") might be part of it.
The first two weeks, with Parker out, Grant and Wilson pretty much split his snaps. Did the offense look better? No, so we'll probably see more of the same for the immediate future.
