Even after New England added corners Darelle Revis and Brandon Browner, Mayo is reserving any judgment about how those players will help until he sees the Pats defense on the field.
"It's always good when you can add talented football players and people who love the game," Mayo said. "We really don't know yet. We haven't been out on the field and gelled together. Obviously there have been talented teams that haven't played well together. We'll have to wait and see and take it one day at a time."
They finished 8-8 and didn't qualify for the playoffs.
"Just as a player and as a fan of football, you kind of notice things like that. These teams, these Dream Teams, that don't pan out the way that you think they will," Mayo said. "Or a player will try to go into a different scheme and it just doesn't fit right or it doesn't work out right. It's all about taking it one day at a time, building the camaraderie, going out there in training camp, going out there in 7-on-7, these workouts together and just getting on the same page."
