PITTSBURGH -- Fresh off signing a blockbuster five-year, $72.7 million contract extension, Steelers wide receiver Antonio Brown said he knew this day would come.

"Had a conversation with [team president] Art Rooney last summer, and once he gives you his word, he sticks to his word," Brown said from the podium, wearing a flower-print suit and supported by his family in the front row.

Rooney introduced Brown on Tuesday, calling his playmaker "one of the hardest-working players we've ever had on our team." That work ethic led to four straight 100-catch seasons and an extension that pays out $68 million over four years, making Brown the league's highest-paid wide receiver. In 2017 Brown will play under his $4.7 million salary from his original deal.

Brown said he was excited after signing the contract Monday night and speaking with quarterback Ben Roethlisberger.

Less than two months ago, Brown was addressing the media over his Facebook Live mishap in the locker room. This news conference set a different, happier tone, but Brown still addressed his character. Asked whether coach Mike Tomlin expressed any etiquette concerns before signing the deal, Brown said, "not really."

"There's always room to grow," Brown said. "I can be more of a better leader, being vocal. We all can get better. ... I never come into the year thinking about the numbers and such. I want to be accountable to being my best self."

Brown, 28, has made it clear he wants a Super Bowl more than receiving records.

"There's going to be a lot of pressure in that regard," Brown said about helping Pittsburgh win a seventh Super Bowl. "That's always been the Steelers way. We have to find a way. We've got our health right here. We can't make excuses. Still a long way to go, a new journey moving forward."

Brown also said running back Le'Veon Bell -- who on Monday received the franchise tag worth $12.4 million -- is a "special" player whom he would like to have around.
