Campbell is starting to see a difference in a team that had lost five in a row after opening the season with a win.
"We battled. We're starting to come as a team a bit more now and have faith in coming back," Campbell said. "Earlier in the season, we didn't have a whole lot of faith and confidence. But now we're starting to see our team develop."
Notes: Vanek has a point in the eight games he's played after missing one because of a muscle spasm. He's now had a hand in six of Buffalo's past seven goals over a six-period stretch, dating to the third period of a 7-4 win at Boston on Thursday. ... The Panthers opened a four-game road trip without D Ed Jovanovski and LW Scottie Upshall, who are both out with lower-body injuries. ... Parros' goal was the Panthers' tough-guy's first point in nearly a calendar year, dating to a goal he scored at Detroit last Feb. 10.
