Three quick hits on the Indianapolis Colts:
1. Jim Caldwell will be a steady leader. Sure, there is still some adjusting for a team led by Tony Dungy for so long. But Caldwell has a similar demeanor, and the first time this team faces a crisis and looks to him, I expect it'll like how he responds. Too much has been made of other changes on the coaching staff. Tom Moore and Howard Mudd are back in place leading the offense and offensive line, respectively, after retirements that helped with their pensions. And new defensive coordinator Larry Coyer and special teams coach Ray Rychleski replaced coaches many thought Dungy had been loyal to for too long.
2. The defense is bigger and more physical. Philip Wheeler and Clint Session are more rugged as the outside backers. The interior defensive line is much bigger with Ed Johnson back and rookies Fili Moala and Terrance Taylor in the mix. That should mean the team fares better in run defense, but all these guys can run too, so the team hasn't sacrificed its dedication to speed. Look for more variety on defense, as indications are a Cover-2 team will play more man and do more blitzing. Whatever the new wrinkles to the scheme, the mindset is more aggressive. Safety Bob Sanders many not be ready for opening day but the team has an excellent fill-in with Melvin Bullitt.
3. Marvin Harrison was hardly himself last year, and while not having him makes things different for Peyton Manning, he's got a solid stable of weapons with Reggie Wayne, Anthony Gonzalez, Dallas Clark, Joseph Addai, Donald Brown, Austin Collie and Pierre Garcon. While protection and run blocking are issues at the start, firepower shouldn't be. Addai looks primed for a rebound after a second-year slow-down and Brown is a more dynamic second option out of the backfield.
