I would give him a 7.
He is one of the faster CBs at that level, but I don't think you really need
that much speed. The fastest WR's you'll generally face are 108ish, and those are pretty rare. Also, by the time most WRs get up to that speed, some other WR has gotten open and become the target. Additionally, you should have safety help over the top for some of the plays, allowing you to neglect speed a bit.
The high speed comes at the expense of agility, vision, jumping (imo, but others will disagree), Superior Vision, and Shutdown Corner.
Still, a 7/10 is a good build.
