FOXBOROUGH, Mass. — The New England Patriots trolled the Pittsburgh Steelers on Saturday and then blew them out Sunday night.

A day after the acquiring former Steelers malcontent Antonio Brown, the reigning Super Bowl champions showed they might not even need him, getting 341 yards and three touchdown passes from 42-year-old Tom Brady to beat Pittsburgh 33-3.

“Well, he’s the best in the world,” Steelers quarterback Ben Roethlisberger said. “There’s a reason he’s the best when he’s out there doing his thing.”

Phillip Dorsett caught two touchdown passes, including a 58-yard score, and Josh Gordon — another receiver who wore out his welcome elsewhere — caught one TD pass. On the night New England unveiled its sixth NFL championship banner, Super Bowl MVP Julian Edelman caught six passes for 83 yards and also completed a throw to help the Patriots begin their title defense.

No one has won back-to-back NFL titles since New England did it in 2003 and ‘04.

Facing the last team to beat them, back in Week 15 last year, the Patriots opened a 20-0 lead before Pittsburgh kicked a field goal on fourth-and-goal from the 1 with 10:17 left in the third quarter. Brady responded with a 58-yard touchdown pass to Dorsett and a 27-3 lead.

Dorsett had four catches for 95 yards and the first multi-score game of his career. He will be moving down the depth chart Monday when the Patriots are expected to make Brown’s signing official.

The move couldn’t be welcome in Pittsburgh. Unable to get Brown to behave, the Steelers refused to trade the disgruntled diva to New England only to see him wind up with the team that has reached the AFC championship game eight straight seasons.

Roethlisberger completed 27 of 47 passes for 277 yards and an interception, though 116 of the yards came on non-scoring drives in the fourth quarter with the Steelers down four scores. The offense showed the effects of losing two of its biggest playmakers: Brown, who talked and tweeted his way out of both Pittsburgh and Oakland in one offseason, and running back Le’Veon Bell, a two-time All-Pro who sat out all of last season to avoid a franchise tag.

In their place, James Conner gained 21 yards on 10 carries; the Steelers gained only 32 yards rushing in all. Top receiver JuJu Smith-Schuster caught six passes for 78 yards, 26 of it coming on one throw in the final six minutes with the Steelers already trailing 33-3.

The drive ended when Roethlisberger threw it into the end zone from the 41-yard line and was picked off by Devin McCourty.

The Steelers had five full possessions in the first half and punted on four of them, going three-and-out three times.

BANNER NIGHT —The Patriots made room for another Super Bowl memento above their south end zone.

The team unveiled their sixth championship banner before the game in a ceremony that included fireworks and a highlight video projected onto a screen covering much of the field.

Drew Bledsoe, Ty Law, Willie McGinest, Rob Ninkovich and Martellus Bennett brought out the first five Lombardi Trophies. Owner Robert Kraft brought out the one the team won in February by beating the Los Angeles Rams 13-3 — the one that was dented by Rob Gronkowski when he used it for batting practice at the Boston Red Sox opener.
