San Francisco 49ers cornerback Richard Sherman and former NFL great Darrelle Revis had a spat on Twitter after the NFC Championship game Sunday.

Revis, who is retired and has not played in the NFL since the 2017 season, criticized Sherman’s defense against the Green Bay Packers. Revis tweeted a picture from his home calling out the 49ers star.

“Fear of getting beat in man to man coverage. Every snap every play. The fact that he doesn’t travel as a cornerback is lame. Except [sic] the challenge as the best and shut Adams down the entire game. Do it for the game of football. Stop hiding a cover 3 zone,” Revis wrote.

The one-time Super Bowl champion then defended himself, saying he wasn’t trying to “shade” Sherman.

“All y’all think I’m throwing shade. I’m not. Just stating the man is not a pound for pound man to man corner. If you know the game of football he plays in a Cover 3 Scheme. He does not travel but traveling with a receiver is not for every DB. It’s a few on the corner list who can,” Revis wrote.

Sherman, who had the game-ending interception on Packers quarterback Aaron Rodgers, replied to Revis.

“I would go in on this has been but I have a Super Bowl to prepare for. Enjoy the view from the couch. Your ninth year looked a lot different than this. Lmao,” Sherman replied.

The three-time First Team All-Pro also took exception to Revis’ “pound for pound” remark. He tweeted a picture of a wide receiver beating Revis.

Revis also commented on his stats in his ninth year in the NFL compared to Sherman's.The 49ers cornerback also responded.

While anyone can debate who’s had a better career, both players are considered some of the best defensive backs over the last 15 years.
