1. Offensive line: This unit is vital to San Diego’s hopes. Injuries made a mess of the line last year, though it improved down the stretch. The 2011 season showed San Diego that it needed better depth on the line, and the team thinks that was accomplished during the offseason -- making this an important night for the entire unit.
2. Defense has to get off the field: A major point of emphasis during Chargers camp has been third-down defense. And for good reason: San Diego was the worst in the NFL on third down last season, allowing opposing offenses to score a first down on 49.2 percent of all third-down situations. That was the worst mark in the NFL in 16 years. We will see if the first two weeks of the John Pagano regime on defense have helped in this crucial area.
3. The rookies: The Chargers are thrilled about their rookie class, particularly first-round pick Melvin Ingram (pass-rusher), second-round pick Kendall Reyes (defensive end) and third-round pick Brandon Taylor (safety). The group has been terrific in camp; let’s see how the players react in a game environment. The team is counting on Ingram and Reyes to play a lot this season, so this will be a good first test.
