"It's going to be tough to make a decision, but it's a pretty good situation," said Gray, who won't pick his starting duo until after the Aug. 30 preseason finale against the Jaguars at Jacksonville. "We have three No. 1 guys. Sometimes in preseason, you'll see Carlos and Shawn, then you'll see Carlos and Fred and the next thing you know you'll see Fred and Shawn. I'm going to be lobbying for nickel, when you can get all three on the field. It's about how we best match up with the opponent's receivers."
