What were the season-crippling mistakes by Brady? List them and we can discuss. Belichick's are well documented and discussed. If you want equitable treatment, then you first need a starting point... so go for it.
Tom Brady is the greatest of all time, but please stop implying that everything he does is perfect. As for examples we can start with the SB 46: safety, incompletions resulting in red zone FG, two incompletions leading to a 3-and-out, another 3-and-out followed by a critical 4th quarter pick; it wasn't a good game. This coming on the heels of a 0 TD/2 Int game vs Baltimore in the Billy Cundiff game, the Pats winning despite Tom. 28 incompletions in those two games combined.
The previous year in the playoff loss to the Jets there were far too many incompletions resulting in the Pats having to punt Tom got hot on the final two drives but by then it was too late, down by 10 with 3 minutes to go. On the first eight drives he went 20-32-183 yards, 1 TD, 1 Int. The pick gave the Jets the ball on the New England 12, and the game was essentially over on a 4th quarter drive with five minutes left that ended on back-to-back incompletions and a turnover on downs.
That Jets game was the second year in a row of one-and-done for the Pats. The previous year Brady completed just 54% of his passes while throwing three interceptions against the Ravens. Go back one more year to the AFCCG vs San Diego, who were averaging 26 points per game. The Patriots won because the defense limited the Chargers to 12 points, bailing Brady out of a 209 yards, three-pick game. The next game was the loss to the Giants with Tom throwing 29 incompletions, losing a critical fumble just before the half, and basically doing almost nothing on seven of the nine drives.
In the 2006 AFCCG the Pats defense scored on a pick six, and the offense started on the 40 or better five times - but that great field position resulted in only one TD and two FGs. Tom's 4th quarter drives consisted of a three-and-out; starting on the Colts 43 and having 1st down at the 13 but two incompletions resulting in settling for a FG; starting on the 46 but two more incompletions leading to another FG; an incomplete pass to Troy Brown resulting in a critical three-and-out; and the game ending on an interception.
2012 post-season: only 53% passes completed (29-54), 1 TD, 2 Int in 28-13 loss to Ravens. 2013 post-season: Pats fall behind 23-3 to Denver, with Tom going 13-22, 133 yards, 0 TD over the first three quarters while the outcome was still in doubt. 2015 post-season: Ton completes just 48% of his passes, with 1 TD and 2 Int in the 20-18 loss to Denver. Of the 60 times Brady dropped back to pass, 33 times the result was no gain and 16 were for a gain of less than ten yards. One of the pick led directly to a Broncos touchdown, and the only TD came after a turnover gave the Pats possession deep in Denver territory. 2019 post-season: 54% completions, 0 TD, 1 Int (pick-six). Zero points in the second half; last six drives consisted of a turnover on downs, four straight punts and an interception.
Despite these and other failures, Tom is still the greatest of all time. But unlike you and a vocal spoiled minority here, I don't paint the Patriots in black and white, nor find a need to stir the townsfolk into gathering their pitchfork and burning a witch.
Belichick made Brady great.
