Tom Brady, who won seven Super Bowls and is widely considered the greatest National Football League quarterback ever, said on Wednesday he was retiring, a year after he made the same announcement only to change his mind weeks later.

Unlike his first retirement, when he made the announcement in a lengthy well-crafted post on social media, this time Brady was short, direct and seemingly spontaneous looking as if he had come to the decision while out for a morning jog.

"Good morning guys I will get to the point right away, I am retiring for good," said Brady, at times struggling to contain his emotions during a 53-second video message posted on Twitter.
