The inability of the Colts' "D" to stop Texans RB Arian Foster in Week One reminded a source close to the team of the 44-17 dismantling at the hands of the Jaguars in Week 14 of the 2006 season. The Jags piled up 375 rushing yards on 42 carries (8.9 yards a clip) that afternoon. The way we hear it, the striking similarity between the two defensive meltdowns stemmed from poor gap integrity. "When guys are trying to do too much, they can become undisciplined," the source said. "They start leaving their gaps and overrunning plays, causing the defense to be vulnerable." A big chunk of Foster's team-record 231 yards came on cut-backs, when he found an open gap and exploded through the hole. Word is the Colts are confident that the run defense will bounce back in a hurry, as long as the players do a better job of playing more disciplined football and allowing the scheme to do its job.
