The Boston Globe's Bob Ryan joined Gary Tanguay and Kirk Minihane on Early Edition where the three discussed the greatest personal rivalries in sports history.
It was a consensus opinion about which rivalry has been the best as of late.
Talking about Tom Brady and Peyton Manning, Ryan said, "It's the best rivalry of the 21st century, there's no doubt about it."
He went on to discuss the best rivalry ever.
"But the best rivalry of all time, the standard of which they're all attaining, is clearly [Wilt] Chamberlain and [Bill] Russell. We have to start with that and go elsewhere.
But is Brady and Manning perhaps the modern day lesser version of Chamberlain and Russell? Kirk Minihane sees it somewhat.
"There's some similarities there," Minihane said. "Now, Manning is not as dominant as Chamberlain was statistically, and Brady hasn't won as much as Russell, but you have a guy with the numbers, and you have the guy with the wins."
Ryan agrees with Minihane's point. The three go on to discuss the legacies of both Brady and Manning.
