TAMPA, Fla. -- Cam Newton pranced into the end zone, placed his hands over his chest and did his familiar Superman pose. He's says the surging Carolina Panthers are hardly a one-man show, though.

An efficient Newton threw two touchdown passes and ran for another score Thursday night to pace a 31-13 victory over the winless Tampa Bay Buccaneers.

The Panthers (4-3) won for the fourth time in five games following an 0-2 start and climbed over .500 for the first time in five years. They've won three straight, with Newton throwing for 667 yards, six TDs and no interceptions.

"It's the culmination of a lot of things," said Newton, who also has two rushing touchdowns in the past three weeks.

"When you've got an offensive line that's protecting the way they protect, when you've got a running back that's running, you've got receivers making plays after the catch, it's really not hard," Newton added. "It's just up to me to make the right decision and get the ball into people's hands that it needs to be."

The Bucs (0-7), one of two NFL teams yet to win, have dropped the first seven games in a season for the seventh time in franchise history. They've lost 12 of 13 dating to last year, and some fans showed up at Raymond James Stadium carrying signs and wearing paper bags over their heads urging that second-year coach Greg Schiano be fired.

"We got licked," Schiano said, adding that calls for his dismissal haven't become a distraction for him or his players.

"It doesn't affect me. `People are certainly entitled to their opinion. ... You sit there and cry about it, but that's not going to help."
