Hard to disagree, but I will.
Rivers is better than Rodgers currently. Why?
He has surpassed Dan Fouts' NFL record in passing yards through 8 games.
In the majority of games, he has been down and the Chargers have had to pass - making it easier for the defenses to read.
He has had 5 300+ yard games in the first 8 games.
He has managed to accumulate these record numbers without his number 1 WR (and number 2 WR for the last 2 of the 8 weeks).
This isn't a fluke, last year he passed for 4254 yards with a passer rating of 104.5 and 28 TDs. The year before 4009 yards with a passer rating of 105.5 and 34 TDs.
If this was Peyton Manning, he would be given the MVP already.
I could also make cases for Brees and Big Ben vs Rodgers.
