The Patriots’ drive for perfection is still on. With one playoff game down and a perfect 16-0 regular season, the Patriots are just two victories away from the perfect 19-0 season. On Sunday 1/20/08 the San Diego Chargers will represent the next obstacle in their way. To the surprise of many the Chargers were able to beat the Colts at home last week, setting up this week’s matchup with the Patriots. The two teams met earlier in the year with the Patriots coming out on top 38-14. If the Chargers are to do better on this go-around, they may have to do so without starting QB Rivers. Rivers was injured early in last week’s game against the Colts.
