TAMPA, Fla. — The attitude has been replaced by gratitude. Other than that, Antonio Brown is playing like one of the greatest receivers in NFL history again.

That’s a scary thought if you’re an opponent of a Bucs team that already has Mike Evans, Chris Godwin and Scotty Miller, as well as big pass-catching tight ends Rob Gronkowski and O.J. Howard.

At 33, Brown had knee surgery in the offseason, but he bears no scars from the off-field trouble that resulted in an eight-game suspension to start 2020.

“A.B. is in great shape and obviously the knee is fine,” coach Bruce Arians said. “Having heard it all again, having been out of the system for a while and getting back in, getting all the practice time and the meeting time — he’s still a great, great football player.

“He’s playing at a speed I saw four or five years ago.”

Given his recent spate of trouble — the messy split with the Steelers that resulted in a trade to Las Vegas, the unexcused absences and inexcusable behavior that led to his release from the Raiders and Patriots — what’s lost is that Brown is second only to Julio Jones among active receivers in the NFL with 11,746 receiving yards.

He joined the Bucs at the midway point of last season, trying to work his way back into shape and into the good graces of Arians, who was his offensive coordinator with the Steelers for several years.

Brown still managed to catch 45 passes for 483 yards and four touchdowns in the regular season, then added two more scores in the playoffs, including a TD catch from Tom Brady in Super Bowl 55.

“Life last year was uncertain,” Brown said. “A lot of uncertainty. Will I even get the chance to play football? Being suspended. So I’ll always remember at that point last year where I was at to make sure I appreciate having the right perspective and being grateful that I’m in this point right here.”

During one media session Monday, his first since the Super Bowl, Brown said he was grateful, excited or appreciative nearly two-dozen times.

“I’m beyond grateful to be here at this moment right here with my teammates at training camp,” Brown said. “I’m putting my hand in the pile and putting my conditioning on display. I don’t take for granted being here. (I’m) thankful I have great health. ... I’ve got the best training guys here. I’m just happy to be here right now and do what I love and play football.”

Even the Bucs were hesitant to re-sign Brown until after he reached a civil settlement with his former trainer, Britney Taylor, who had accused the veteran receiver of sexually assaulting her.

By then, Brown’s free-agent market had all but dried up and he reached an agreement with the Bucs.
