Dolphins WR Mike Wallace isn't a strong practice performer, he struggled in his contract year and he's just been set with generational wealth. I heard that Dolphins corner Nolan Carroll, not exactly a household name, pretty much had his way with Wallace through OTAs, he's already been nicked up in preseason and he's a guy who shows up in flashes more than on every drive, the way you would expect the fourth-highest paid receiver in the game to do so.
We're skeptical that Wallace will have a big impact in his first season in Miami, especially since he has had trouble building chemistry with QB Ryan Tannehill. We currently have him ranked #30 in standard formats.
