Speed does not mean you are a great football player. I would concentrate more on his position specific attributes like MCV, ZCV, PRC, and PRS which are all in the upper 90s. If there is a speedy WR who is fast but has a release rating of 50 or a route running of 60 he will get shut down. Don't worry too much about it. This system is specifically designed to allow individual attributes that are position specific to be at the forefront.
