Carolina Panthers defensive end Charles Johnson has racked up 62.5 sacks, 203 tackles, 16 forced fumbles and 21 pass breakups in his 8-year career. He’s never had an interception. But the man nicknamed ‘Big Money’ provided the biggest highlight of Thursday’s OTA practice, snagging a pick from the guy now making even bigger money.The Panthers spent a good chunk of the day working on their 2-minute offense, and quarterback Cam Newton, who signed a 5-year, $103.8 million extension Tuesday, had already found Ted Ginn and Devin Funchess for touchdowns. After each, Newton made a vocal sprint to the end zone to celebrate with his receivers.Then, on the opening play of the first-team offense’s fourth 2-minute drive, Newton looked flicked a dump-off pass to fullback Mike Tolbert. That’s when the 6-foot-2, 285-pound Johnson jumped and snared the ball with one hand. Almost immediately — like it was a game of hot potato — he tossed it back to Newton. And as the defense celebrated, they let Newton know about it.“Any time you get a pick on Cam, you’ve got to have fun with it, cause if he scores, he’s going to have fun, right?,” Johnson said.But you didn’t want to keep the ball?“Let him have it, tell him get back and do it again,” he replied.“He was a little salty about that. Any time a D-lineman catch a pick on a quarterback, they’re going to be salty.”It was all in good fun for a group of guys finishing up their workweek. But it was an especially spirited day for a practice in early June.“Guys had a lot of energy, especially for an OTA practice. I was excited about their effort. The guys were really having a good time competing against each other, challenging each other,” head coach Ron Rivera said. “It was a lot of fun to watch those guys compete.”Despite a couple mistakes — he was also intercepted off a tipped pass — Newton continued to throw the ball well while tossing in some scrambles and designed runs.It’s also apparent his new money won’t change the playful attitude he brings to most practices. Newton pretended to run away from the media “paparazzi” when a golf cart dropped him off, and his was the loudest voice on the field for nearly two hours. And even though the defense seemed to be talking back a bit more on Thursday, at least one teammate claimed it nothing to do with wanting to one-up the NFL’s newest $100-million man.“I don’t even think I see that when I come out here,” cornerback Josh Norman said. “I just see a competitor, and I want to compete with one of the best competitors in the game, so it makes us better.”
