I don't think anybody's questioning Brady's overall accomplishments. But has he gotten lucky in recent years? Yes.
Let's rewind to 2018. Trailing by 4 with under a minute left in the AFCC, Brady throws his 3rd INT of the night, but it's negated because a LB was lined up a few inches offsides. Goes on to win the SB despite only scoring 13 points, because his defense holds the opponent to 3.
The next season he has the best defense in the league (best scoring defense by a wide margin) and he loses the first playoff game to a Titans team with no defense. Scored 13 again.
Next he finds himself in Tampa Bay with a group of WRs that were being called the best in the league. Then he adds Gronk and Antonio Brown. And as usual he has a loaded defense. The media says he's "rejuvenated!" He wins the NFCC in Green Bay despite three INTs in the 2nd half. Then he throws for 200 yards in the SB, gets 120 penalty yards, and watches as his defense becomes the first to ever hold Mahomes to single digits.
Bringing up the 7-9 record is just lazy. Their offense put up more yards last year with fewer weapons and a QB who was NO's 3rd-stringer this season. And their defense went from terrible to great. Not sure what Tom had to do with that.
He hasn't been a world-beater in recent years but he still gets all the credit.
