No, you stop. Really! Special teams is schemed as well. Many great returners could not be great WRs. Hester is far more dynamic than Edelman yet not a great WR.
Look at Edelmans catches, over half are 5 yard routes he catches before reaching a single DB! Watch his highlights. He barely averages 10 ypc. He is great at what he does! But no other team would want him as their #1 while looking for Dobson as just his compliment. He rarely snatches passes over the middle at 15-20 yard range or deep like #1 WRs are expected to do. Again not a knock on him, he is very good at what he does but that's not #1 WR stuff.
