Antonio Brown took accountability for a series of actions he has taken on and off the field over the past year that has put his future in the NFL in jeopardy.

"I think I owe the whole NFL an apology and my past behavior," Brown told Anderson. "I think I could have done a lot of things better."

Brown spoke two days after Roger Goodell said the league's No. 1 concern is Brown's well-being.

"I was pleased to hear that after 140 days that there was some positivity about me because as of late I've just been the cancer of the NFL," Brown said, referencing Goodell's comments at his state-of-the-league address Wednesday. "The problem child, the guy who gets in trouble, the kind of guy who has the bad narrative about him."

Asked whether he believed Goodell, Brown told Anderson: "I'll believe it when we see it."

Asked whether he needs mental health help, Brown added: "We all need mental help."

Brown has been accused of sexual assault by two separate women, which the NFL continues to investigate.
