I went back and looked at TB's playoff states from Snow bowl game until last weeks with Baltimore. I only focused on TD's vs INT's
From 2002 to 2005
11 TD's
3 IINT's
From 2006 to 2112
25 TD's
16 INT's
I chose 2006 to differentiate because it was the first playoff game (denver) that TB threw more than 1 INT (i actually that it was more). It was also his First playoff loss, up until tha game he was 10-0. I had to use more than one site to get the figures. It was 330 am when i started trying to count up the INT. vs TD i'm not sure i added them up correctly, but it should be close.

Tom Brady Has Only Played One Good Playoff Game Since 2008, And We Have No Idea Why - Business Insider
2008 against the Giants: 29/48, 266 yards, 1 TD, 5.54 yards per attempt
2009 against the Ravens: 23/42, 154 yards, 2 TDs, 3 INTs, 3.67 yards per attempt
2011 against the Jets: 29/45, 299 yards, 2 TDs, 1 INT, 6.64 yards per attempt
2012 against the Broncos: 26/34, 363 yards, 6 TDs, 1 INT, 10.68 yards per attempt
2012 against the Ravens: 22/36, 0 TDs, 2 INTs, 6.64 yards per attempt
The Broncos game was his only truly good game, the first Ravens game was his only truly bad game, and the other three were below average compared to Brady's regular season numbers.
"But another theory is that the league's best teams — despite all the chatter over the NFL becoming an offense-first league — still consistently have the best defenses.
"Every Pats opponent except the '11 Broncos and the '08 Giants had a top-5 scoring defense, and that Giants team didn't allow more than 20 points in any playoff game that year."
"But Brady was excelling against the stiff competition in the playoffs between 2002-05. So why has he fallen off recently?"
I have a couple of theories one of which is that in the first 4-5 years the offense was more diversified, it was balanced more between pass vs run with Smith and Dillon. After Dillon it became more of a passing offense that relied more heavily on Brady to make it function. Opposing defenses could focus on stopping TB.
The other i mentioned before a couple of times, hes pressing for what ever reason. Maybe trying to hard to live up to the legend he created.
After the loss to Indy in the AFCCG in 07 the pats became more of an offensive minded team, therefor more points had to be scored, and TB had to throw more. Up until then the Pats were a team with a very good defense that kept the other team in check. They didn't need to score a lot of points to win.
