Tkachuk, acquired by the Panthers in a trade with the Calgary Flames on July 22, has two goals and an assist in his first two games with Florida.
"I said it at the beginning of the year, points, individual stuff like [that], I'm past the point of caring about that stuff," Tkachuk said. "I don't care what the individual stuff at all. I'm here to win games and I'm having a great time doing, it. … It's an unbelievably tight group and I'm very lucky to be a part of it."
Aleksander Barkov had two assists, and Spencer Knight made 24 saves for the Panthers (2-0-0).
"I thought we got stronger in the defensive parts of game as this game went on," Florida coach Paul Maurice said. "… [The Sabres] played hard, they've got lots of skill. It's a good young team, right? So, they're never out of it. … Got a real big save from Spencer when we needed it. So, everybody had a little piece. But I think penalty kill and power play were the defining pieces to our game today."
