Broncos cornerback Champ Bailey is a 10-time Pro Bowler, but he knows he'll have his hands full on Sunday against Lions wide receiver Calvin Johnson. The last time the two players faced off, in 2007, Johnson was just a rookie. "Back then, he was a young pup," Bailey said. "He wasn't polished yet, but he's figured that thing out real fast. He has no issues now. He's using everything he has -- size, strength, all his speed. You see all the different parts of his game coming out." Through seven games in 2011, Johnson leads the NFL with 10 touchdowns receptions. He ranks third in receptions and fourth in yards as well. "I think one guy could be successful, but it does take a team effort to defend him all day," Bailey said of defending Johnson. "You can't just match up on him and think it's going to work all day, if he has a good quarterback throwing the ball. There's sometimes when he goes up, nobody can get to that height that he reaches. He's about as tall, strong and unique as they come."
