Now W/L, QB rating, TD:INT ratio, and TD% are "cherry picked stats?"
Huh. It's almost like the most important stats are all really really good and don't support your argument.
The playoffs are the hardest place to play. You play the best teams, which is why QB's like Brady have passer ratings in the 80s in the postseason. And Flacco having comparable and sometimes better numbers in the postseason compared to the greats matters a lot. That's not average. Average QB play in the playoffs isn't on the heels of guys like Brady.
I can't convince somebody who is willing to be wrong.
