There is no debate that Chad Henne is a lesser quarterback than Philip Rivers, yet Henne still finished the game with 416 yards and two touchdowns to only one interception. Henne didn't have to make that many difficult passes either, which was really telling for the Patriots defense.
Brandon Marshall had a huge day, finishing the game with seven receptions for 139 yards. What isn't reflected in the statistics is that Marshall also dropped an easy touchdown reception. The Patriots struggled to deal with Marshall's size.
If they struggled to deal with one tall receiver, what will they do with three of them?
Vincent Jackson is a better player than Marshall with sure hands and a bigger physical presence. He will be able to have similar opportunities to what Marshall did this week. Malcom Floyd across from him will cause more matchup problems, while Antonio Gates could dominate against that inexperienced safety group.
With those options ahead of him, Rivers could be set for another huge day. When your fantasy quarterback has a bad day and still puts up 335 yards and two touchdowns, you generally don't ever consider sitting him.
However just in case you had someone like Sam Bradford or Cam Newton on the bench and were considering bringing them in, don't give it another thought.
