Five nuggets of knowledge about Week 2:
Line makeup: We came into the week thinking Colts newcomer Trai Essex could take over for Winston Justice at right tackle, but Justice seems to have bounced back from the concussion he suffered Sunday in Chicago. He’s practicing and it’s left guard Joe Reitz who remains a question. Seth Olsen is not a quality replacement, and Essex is versatile enough to play either guard or tackle spot. Perhaps he replaces Olsen rather than Justice? The No. 1 question on the offensive line will be how left tackle Anthony Castonzo can do against end Jared Allen, who was largely held in check last week by Jacksonville’s Eugene Monroe.
Line makeup, II: The Jaguars are banged up in a big way on the offensive line. Starting right tackle Cameron Bradfield and starting left guard Eben Britton could both miss the game with ankle injuries, which would mean Guy Whimper or waiver claim Troy Kropog at right tackle and undrafted rookie Mike Brewster at left guard. That’s hardly an ideal scenario against the Texans’ swarming front. It looks like a big mismatch. But often what looks like a big mismatch in a divisional game during the preparation week doesn’t turn out to be the major issue.
Struggling in Cali: The Titans have lost eight in a row against the Chargers, dating all the way to 1993. San Diego’s 3-4 front has given Tennessee problems in recent years, and first-round draft pick Melvin Ingram, an outside linebacker, is a part of packages that will be another complicated thing for Jake Locker to sort through. The quarterback will be playing with a banged-up left (non-throwing) shoulder. But he will be throwing against a banged-up secondary too, so if he can get protection he may be able to find plays downfield with Kenny Britt back in the lineup.
Playing stout: The Colts allowed 3.5 yards a carry in their season-opening loss to the Bears. That wasn’t as bad as some of us anticipated it could be. But Minnesota’s Adrian Peterson will be a different level of challenge. He found the end zone twice in his first game back with a reconstructed knee in the Vikings' win over Jacksonville. The Colts remains susceptible to the run and are going to get tested. If and when they can get the Vikings into tough passing downs, will Dwight Freeney be available to chase Christian Ponder? If his ankle injury holds him out, the Colts are then deficient in that area as well, which would be bad news.
Improvement: Good teams respond to week-to-week problems. Texans coach Gary Kubiak wasn’t pleased with the way his team ran the ball and the way it performed on special teams, even though it posted a 20-point win over Miami in the opener. His players should respond to points of emphasis and show improvement in those areas. Jacksonville’s big point of emphasis has been better tackling, and it will need to wrap up the likes of Arian Foster and Andre Johnson to have a chance in this game. Outside linebacker Daryl Smith would be a boon, but he looks unlikely to make it back from a groin/abdomen injury. If corner Derek Cox is back from his hamstring problem, coverage should be a strong suit.
