3-cone times - Beasley 7.16, Welker 7.09, Gunner 6.88 and Edelman 6.62. So Gunner is quick enough. I think you are wrong on this like you want to be
I agree that Edelman looked quicker than Welker (because he is), and Gunner does not look as quick as Edelman (because he isn't) during his punt returns, but Gunner had the highest punt return average in the NFL in 2020 (for players with 10 or more attempts), and will only get better. Gunner has a unique combination of quickness and vision. So I am sure Gunner can be a slot receiver as he has the natural quickness and the vision needed. Does Gunner know how to read the defense and find the holes like Welker and Edelman? I do not know. Not sure Cam could read a defense after 10 years. Are Gunners hands OK? I do not know. Hopefully it all comes together for him with one more offseason.
