What went wrong ...
1 Secondary collapses late — Although they were stout for most of the game, the Giants’ defense couldn’t hold a six-point lead with 2:07 left. Philip Rivers led San Diego on an eight-play, 80-yard drive in only 1:46. The drive culminated with Rivers finding Vincent Jackson on an 18-yard scoring strike.
2 Short yardage — The Giants failed five times on on third-and-less-than-4. The most costly short-yardage failure came with less than three minutes left. Up 17-14, Terrell Thomas picked off Rivers and returned it to the San Diego 4-yard line. A holding call on first down pushed them back 10 yards and they settled for a field goal. The one-possession game left the door open for Rivers. “We have to score when the opportunities are there,” Jacobs said. “We got it down on the 4-yard line and didn't punch it in, and the consequence was a loss."
3 Hold that line — The Giants had given up just 10 sacks all season, but the Chargers broke through for five in yesterday’s win.
