Fair point on the food poisoning comment; thankfully I missed the other part you wrote above.
Haven't kept detailed track of his play; just my general impression that some receivers [and maybe they're just those super fast and quick types] get by him or are able to get completions with less difficulty than say a TC.
Think it was this last game but TS was chasing the opposing player on a long run and couldn't catch him; they scored. Later I was watching the Bama game and watched Battle chase down and tackle the opposing player on a long run; preventing the TD. Each situation is different of course, and it may be apples to oranges, but it left me wondering about the sufficiency of his speed to play as a high level CB.
He's also made some good plays and hopefully he keeps improving.
