Chad Henne has a good chance to start for the Dolphins this coming season, according to coach Tony Sparano. "The one thing we've had time to do is a lot of homework and study," Sparano said. "And I would tell you when you put Chad's numbers up against some of the better quarterbacks in our league, his numbers are pretty impressive. They hold up. Now what has to happen? We have to cut down the impulse throws, the interceptions that happen late in the fourth quarter."
