"He can make some of those small-area plays," Cassidy said. "[Backes] is a little more straight forward, chip and chase, get behind. We always felt David played his best hockey [on the fourth line]. It's just we've got [Noel] Acciari there. We've had [Chris] Wagner there. There's only so many roles, I guess, carved out on our team for that style. And David's been fine. He's matched up physically well against this team.
"It's just a decision we've made to be a little different. Maybe [Krejci] sees a few more pucks in the neutral zone and in that case get a little more speed off the rush or speed on the original forecheck. We'll see how it plays out."
Backes, who has five points (two goals three assists) in 15 playoff games, said Saturday he was prepared to sit out again if that was what Cassidy decided.
"We're here to win," Backes said. "If my part's grabbing the pom-poms again, I'll shake those things until all the frills fall out of them."
Kuhlman, who had five points (three goals, two assists) in 11 regular-season games with Boston, said Cassidy told him Saturday there was a chance he might play in Game 6 and confirmed it Sunday morning.
"Obviously, it's been a dream since you're a little kid to play in the Cup Final," Kuhlman said. "I've just got to do everything I can to help this team win. … We know what I need to do to help this team and that's all I can try to do. Not try to be a superhero tonight and just do my job."
