Anyone paying attention the last 20 years would notice that It's the Chase Claypool and Mims Body types in Metcalf, AJ Brown, MT, Mike Evans, Marques Colston, Kelvin Benjamin who excel early as rookies.
Several of those guys don’t have the same body types.
AJ Brown (6’0, 226) vs Michael Thomas (6’3, 212)
Why are you so low on Tee Higgins & Michael Pittman (6’4, 216 & 6’4, 223) if body type is what you’re looking for and they’re close to Michael Thomas?
And Laviska Shenault (6’1, 227) is extremely close in body type to Brown.
I am not saying these guys are anything similar as prospects from a skill set perspective. But basing wide receivers likelihood of success off of something like “body type” is questionable.
Terry McLaurin led rookie WRs in yards per game and he is 6’0, 208 pounds.
