Antonio Brown continues to reach out to those he disparaged during his year out of the NFL.

The free-agent wide receiver addressed former Pittsburgh Steelers teammate Ben Roethlisberger in an Instagram post Wednesday, apologizing for his behavior and writing, "I never realized how good I had it."

Brown has gone on something of an apology tour in the wake of his arrest for felony burglary with battery, among other charges. It was the latest in a long line of off-field incidents for the wideout, who is also still under investigation by the NFL for allegations of sexual assault and sexual misconduct.

Last week, the 31-year-old started trying to repair the bridges he'd burned in Pittsburgh. He admitted he became a distraction and praised the Steelers organization for "so many amazing moments."

Brown has routinely attacked the NFL on social media since his release from the New England Patriots after one game in September, and the likes of Roethlisberger and JuJu Smith-Schuster have also drawn his ire.

In a December tweet, Brown called his former signal-caller a "loser."

Roethlisberger and Brown were arguably the deadliest QB-WR combo in the league during their time together in Pittsburgh.

In nine seasons with the Steelers, Brown put up numbers worthy of the Hall of Fame, catching 837 passes for 11,207 yards and 74 touchdowns.
