Breaking down the Colts offense, defense and special teams

QUARTERBACK Starter: Peyton Manning. Key backup: Jim Sorgi. 2008 grade: A. An infected bursa did what few defenses had been able to accomplish -- slow Manning's air show. No. 18 had 10 touchdowns and nine interceptions during the team's 3-4 start as he wrestled with his timing and mechanics. Then normalcy returned. Over the final nine regular-season games, Manning compiled a 109.7 rating, completing 72.1 percent of his passes with 17 touchdowns and just three interceptions. The Colts closed the season with a nine-game winning streak and Manning earned a record-tying third league MVP.
