This story is obviously click bait. Christ, I was on the site just a couple of hours ago and read where Brady's accuracy on passes over 10 yds was the best in the league. Now just a few hours later and article comes out and where all suposed to be on "cliff-watch".
The fact is that Brady's regular season DID seem like we saw some slippage. It was a fact and at 41 not unexpected. But when the game really mattered, at the biggest moments, NO other QB in the league played better. NO ONE! All those other guys are faster, have better arms, are more elusive, etc, but if your team was faced with a MUST have drive at the end of a game, I don't think you'll find one of those so called "experts" would pick anyone else to head that drive. To pick someone else, (even Mahomes who would be my pick as a close 2nd) would be a Bernard Pollard level observation.
So far this off season, we have no reason to think we will see much 'slippage' either.
