Give him a break. Cut him some slack. The CB is the hardest position to pick up in all football and is not an easy process. He will get burned but he will also make the great plays. Even Champ Bailey got burned during his rookie season. Give him sometime and you will find out why people are calling him a potential shutdown CB. He will be picked on during pre-season and even early in the season. But he'll learn from it and then you will see why he was picked 10th overall in this year's draft.
Just have some patience.
