When the GOAT speaks, you listen, especially when you're a rookie in your first NFL training camp.
That's what Titans wide receiver A.J. Brown did when he crossed paths with then-Patriots quarterback Tom Brady during Tennessee's joint practices with New England last summer.
According to Brown, the 43-year-old quarterback imparted some valuable wisdom on the second-round draft pick -- the best advice Brown has received as a pro -- at one of those practices.

"He told me: Work on the things you know you need improvement on, so you won't have no weakness," Brown said Monday in a video conference with reporters, via Titans.com.
"Everybody works hard, but everybody knows what their weakness is. Work on your weakness so you have no weakness."
That's sound advice from Brady, whose relentless drive to eliminate his own weaknesses helped him win six Super Bowl titles with the Patriots over 20 seasons before leaving for the Tampa Bay Buccaneers this offseason.
It appears Brown took Brady's advice to heart, too: The 23-year-old has been working to improve his conditioning after noticing on film that he looked fatigued during the fourth quarter of games as a rookie, which he believes may have given away some of his routes.
"(I have to) make sure my pad level is the same all the way through the whole route," Brown said. "Just not putting on your turn signal before you turn."
Brown was the only rookie wide receiver to top 1,000 receiving yards last season -- 1,051 yards on 52 catches with eight touchdowns -- so the Ole Miss product could become an elite NFL wideout if he takes another step forward in 2020.
Brady has helped plenty of Patriots wideouts over the years, but he's also been a font of wisdom for other budding NFL stars -- and you can add Brown to that list.
