Nothing he's going to do in his age 43 season when age has been causing him to decline already for a couple of years now (despite whatever he thinks of his ability to play until 45 or whenever) is going to prove jack shit. It's like betting on a fight in which you know one of the guys is going to take a fall and acting like you were smart as fuck for putting your money on the opponent.
Wherever one stands on "system QB or not" as far as Brady goes, this year (and the last couple) isn't going to be a win for people on either side on that debate. It's just going to add to Time's undefeated streak.
