Tom Brady Will Be Amazing Broadcaster

Tim Tebows already so convinced that Tom Brady will be great in the broadcast booth ... he tells TMZ Sports hes hoping the G.O.A.T. will give him TV advice -- not the other way around!!

We got the former Heisman Trophy winner -- whos been analyzing football games for ESPN for nearly a decade -- out at LAX ... and hes guaranteeing TB12 will thrive in a post-football role as a color commentator.

"Hell be amazing," the 34-year-old said. "Hell be so good at it. Hes got so much knowledge and hes such a good guy and kind guy. And, he knows the game too well. Hell be amazing."

Tim, who actually played with Brady during his short stint as a New England Patriot back in 2013, said repeatedly he doesnt have any TV advice to share with Tom -- simply because he believes Brady already has all the tools needed to be the next Tony Romo or Troy Aikman.

"Listen," Tebow said just a few days after Brady signed a monster contract earlier this month to join Fox Sports after his career ends, "Hes the greatest of all time for a reason. Hes going to go up there and hell be amazing. So, truly will."

Theres more ... we also spoke to Tebow about his athletic career and if he was seriously done with sports -- and the former NFL first-round pick/MLB minor leaguer doesnt appear to have closed any doors just yet.
