Much has been made about the relationship -- or lack thereof -- between Tom Brady and Bill Belichick. But less than a week following Brady's retirement, his former coach showered him with praise in what was an emotional exchange between the greatest coach-quarterback combo in league history. 

"The greatest player. The greatest career. A great, great person," Belichick said on Brady's first "Let's Go!" podcast since his retirement, via SiriusXM. "I guess it has to end at some point."

Belichick said he "learned so much" from Brady during their 20 years working together. The six-time Super Bowl-winning head coach said Brady offered him the unique experience of getting the see the game from the quarterback's vantage point. 

"I learned so much from Tom because, as you know, I never played quarterback and I never saw the game through the quarterback's eyes," Belichick said. "I saw it through a coach's eyes. And Tom would tell me what he saw and how he saw it."
