Patrick Peterson and Richard Sherman continued their ongoing Twitter feud on Wednesday after the Arizona Cardinals star signed a bigger contract than his Seattle Seahawks counterpart did.

Peterson and the Cardinals announced on Tuesday that they had agreed to a new five-year, $70 million contract extension, $48 million of which is guaranteed. The new deal contains one more year and more money than the four-year, $56 million contract Sherman signed with the Seahawks in May.

With his new contract in hand, Peterson took to Twitter to tweak Sherman over the fact that he was no longer the highest-paid cornerback in the NFL. “Y u mad bro!!! LMAO,” the Cardinals star wrote on Twitter.

Just 12 minutes later, Sherman, who won a championship with the Seahawks earlier this year, fired back with a scathing retort. “Can’t ever be too mad lmao…,” he wrote, along with a photo of his 2014 Super Bowl ring.

This isn’t the first time Peterson and Sherman have exchanged words. In May, Peterson told ESPN that he believed he was worth more money than Sherman, who is widely regarded as the best cover corner in the NFL. “I’m making OK money right now, but I’m just not making his money right now,” Peterson said at the time.

Soon after, Sherman posted a screenshot of an ESPN stat that identified him as the player with the most interceptions in the NFL over the past three seasons. “Want what I got? Get the stats I got! Least targeted. #opinionvsfact,” he wrote.

Peterson responded by claiming that Sherman’s production level was attributable to the Seahawks’ defensive scheme rather than an indication of his talent. "He's only covering space. He's not really covering a guy," Peterson said during an appearance on Arizona Sports 98.7. "At the end of the day, he has great stats and he has great playmaking ability. Not taking that away from him because he is a good corner.”

Once again, Sherman fired back on Twitter. The Seahawks corner said that Peterson had given “up more Tds this year than I have in my career.”
