This is an interesting question. The Colts have made an amazing transformation in their run defense. They had allowed 173.0 yards rushing per game and 5.3 yards per carry during the regular season which was the worst in the NFL. The Colts have turned into a dominant run defense in the playoffs as they’ve only allowed 63.5 yards rushing per game and 3.4 yards per carry which is amazing. The return of safety Bob Sanders and the insertion of Rob Morris back in the starting lineup have been the major reasons for this improvement. Bob Sanders has 13 tackles and an interception in the playoffs after playing only 4 games in the regular season and registering 27 tackles. With Sanders back, the Colts moved Marlin Jackson from safety to corner and he’s helped out on the run defense too with his aggressive run support. Rob Morris has 11 tackles in the post season after only getting 55 in the regular season. Dwight Freeney also has turned his game back up in the playoffs as he has two sacks after only getting 5.5 during the season. It was his first season in the NFL with less than 11 sacks. The Colts will need him to put pressure on Tom Brady, because if Brady can stand in the pocket the Colts could be in trouble. Robert Mathis will also have alot to say about that as he has 11 tackles and 1.5 sacks out of the opposite DE position. During the regular season, Mathis had 65 tackles, 9.5 sacks and 4 forced fumbles. Cato June has been the glue of the Colts defense all season as he led the team in tackles with 142 and he also intercepted three passes. He’s also leading the team in the post season with 15 tackles.Â
