I can see what you mean by body type, I guess.. but these are all very different WRs.
Mims is more of a deep threat with the skillset to branch out into a complete receiver. His ceiling probably looks a little something like Emmanuel Sanders.
Reed is more of an all around receiver that's athletic enough to play all positions but not fast enough to make his money as a deep threat. Ceiling for this archetype is something like Stefon Diggs (although he lacks the same kind of violence in his route running) and part of the reason he's been so productive is being attached to Josh Allen.
Tillman is more of the stereotypical X receiver like Michael Thomas.
Mingo comps more to high BMI, YAC receivers with a vertical element to their game like Deebo Samuel, AJB.
I'm very much not high on this WR class and I believe these are all significantly worse prospects than the ceiling comps I listed... but ya never know how these guys are going to develop in the NFL.
I'd rather trade out of this pick range and grab Michael Wilson a round later and pray he stays healthy but that's not always an option.
