It's a rivalry that hasn't ended simply because one of them retired from the NFL. While Tom Brady works to continue his Hall of Fame career by departing from the New England Patriots and joining the Tampa Bay Buccaneers, the league was forced to say goodbye to the playing career of Eli Manning -- who retired in 2020 when the New York Giants made Daniel Jones the new face of the franchise. The battles between Brady and Manning are the stuff of legend, never to be forgotten, and the former is keeping their friendly competition alive and well even if the latter never again puts on a helmet.

Manning officially broke his social media silence by joining Twitter in late May, posting a single tweet to announce his digital arrival.

Of course, Brady weighed in, and in the only way he knows how: competitively. 

But Manning had a reply of his own, taking the back-and-forth into the world of golf.

Brady having punctuated his friendly jab with a fun emoji made it evident the two are just having a laugh but, with the welcoming, the Brady-Eli rivalry is birthed in the social mediasphere. In the end, Manning will forever have the last laugh though, by virtue of having defeated Brady on two separate occasions in the Super Bowl. To add insult to injury, one of the losses came on a magic heave by Manning that stuck to the helmet of former Giants wide receiver David Tyree for a 32-yard gain that led to a game-winning touchdown, landing a 17-14 win over a Patriots team that hadn't lost a single game in either the regular season or postseason up to that point. So when Brady speaks on Manning showing up in the fourth quarter, well, let's just say he hit the nail right on the head. 

As for not joining Twitter sooner? Manning probably sees it the same way he did in Super Bowl XLII, which is to say it's not when you show up, but what you do when you arrive.
