Was Archie Manning the only Saint to get Player of the Year?

I'm so trying to figure out how in the world did the NFL gave the MVP to Peyton Manning over Drew Brees in the 2009 season.

2009 season
Saints 13-3
Colts 14-2

Brees had more TDs & fewer INTs than Manning. Plus, Brees sat out the season finale due to already locking up #1 Seed. But Manning had more than 150+ yards & 1 more game than Brees
Both teams had 3 losses after everything was said and done!😁
