Dolphins cornerback Vontae Davis gets to try figuring out how to slow down his wrecking-crew tight end brother Vernon (left). Meanwhile, the Dolphins look at what might have been with Jim Harbaugh (center right, with Alex Smith) on the other sideline. Owner Stephen Ross pursued Harbaugh after the 2010 season, only to be passed over in favor of the Niners. The 49ers have a talented young defense, led by linebacker Patrick Willis (right).
