Interceptable passes?

"Brady had his worst game of the season in the Super Bowl and showed poor arm strength".

Now, here in the summer of 2017, Cian Fahey from Pre-Snap Reads is stepping to the plate.
Fahey — who has an extensive background covering football for Bleacher Report, Football Outsiders, and Rotoworld, Sports On Earth — wrote an article examining the problems facing older quarterbacks in the NFL. That crop included the soon-to-be-40-year-old Tom Brady. (The story ran on June 29 but started making the rounds in Boston this week.)
Fahey uses “interceptable passes” to evaluate quarterbacks, and even though Brady threw just seven interceptable passes in his 12 regular-season games, he was charted as having thrown nine interceptable passes in three playoff games.
Without a doubt, the win over the Texans was an ugly one, with Brady going 18-for-38 for 287 yards, 2 TDs and 2 INTs. That came against the NFL’s No. 2-ranked pass defense. And surely, Brady had his downs in Super Bowl LI vs. the Falcons, including a bad decision that led to his first-ever postseason pick-six.
But where Fahey is going to lose a lot of folks is when he writes this: “The Patriots won the Super Bowl so Brady got all the plaudits. Yet it was by far his worst game of the season. He repeatedly tried to give the game away.”/
