After extending a couple of his NFL records and continuing his assault on the Steelers' all-time receiving charts, Antonio Brown momentarily let his hair down.
He posed for photos at midfield with Steelers defensive lineman L.T. Walton (inactive), 49ers offensive tackle Joe Staley and 49ers linebacker Nick Bellore.
That might have constituted yet another NFL mark that Brown has a hand in _ four guys from Central Michigan in the same NFL Stadium.
Whether it did or it didn't, Brown enjoyed the moment.
But by the time he made it into the Steelers' locker room at Heinz Field, he was already looking ahead to a tough road assignment in St. Louis this coming Sunday.
"We gotta continue to prepare and get better," Brown insisted after Sunday's 43-18 victory over San Francisco.
Brown had contributed nine receptions for 195 yards and a touchdown and a 16-yard punt return toward the Steelers evening their record at 1-1 by beating the 49ers.
His mammoth afternoon took him to 400 career receptions and beyond in just 72 regular-season games. Only Anquan Boldin (67) and Larry Fitzgerald (71) have gotten there faster (Kellen Winslow also required 72 games).
Brown emerged eighth in Steelers history in yards from scrimmage (5,669), passing Lynn Swann (5,534), surpassed Swann (5,462) for the fifth-most receiving yards in Steelers history (5,587) and tied Buddy Dial for third among Steelers in 100-yards receiving games (18).
And of course Brown extended his NFL-record streaks of at least five catches for at least 50 yards (34 games) and at least five catches for 70 yards (20 games).
"It's always a positive thing," he said. "It's hard, man, it's the NFL. You can't take it for granted."
Even those new to the Steelers could be forgiven for seemingly succumbing to such a temptation.
"Ben played like Ben and 'A.B.' played like 'A.B,'" assessed running back DeAngelo Williams, who tied a Steelers record with three rushing TDs.
And when that happens, the catches and yards and records are sure to follow.
"He's special," Brown said of quarterback Ben Roethlisberger. "He can see the whole field. He can read a defense, he's making checks. And you know about his arm. Any time you have a guy like that at quarterback it's exciting to play football.
"We continue to build through the week of preparation and work. We always communicate as regards to him letting me know what he's thinking, where he needs me to be, (that) he needs me to be disciplined on some routes.
"You could say the payoff comes at game time."
