When you look at the playoff QB's and QB's that make it to the super bowl your looking at 4000+ and 28+ TD's. I know Matt Ryan and Tom Brady easily hit those numbers last year. You cannot get those number without passing for 300 multiple times and multiple TD's.
You could probably go back 5 years and almost every QB in the playoff had 4,000+ and 28+ TD's. I want to get into the playoffs and get to the super bowl, you will never do that with 190 yard passing games.
