After Tom Brady retired from the NFL, Antonio Brown posted a message to Instagram calling him the GOAT.
"Congratulations to the [GOAT] @tombrady ... I'm forever grateful for the opportunity to play with you, thank you for enabling me to continue my career in my darkest times and helping me become a champion. I am thankful for your leadership and winning mentality to make people around you better," Brown wrote.
Shannon Sharpe is calling BS on the message.
"Man, AB is full of it," Sharpe said. "He's just trying to clean up the mess he made. I dismiss everything he just said. I already know how you feel about Tom Brady, you've told me how you felt about him."
On his podcast, Brady explained his retirement: "I said this a few years ago, it's what relationships are all about," Brady said. "It's not always what I want. It's what we want as a family. And I'm going to spend a lot of time with them and figure out in the future what's next."
