This season, that 3M Line has done it all, much of the heavy lifting, for the resurgent Flames.
Backhand's stellar play down the middle has drawn richly-warranted Selke attention. Tkachuk's particular, eye-catching blend of corrosive and commanding is already morphing him into a fan favorite.
Meanwhile, in a characteristically quiet, understated style, Frolik has tiptoed to within three points shy of a career-high, 45, set in his rookie NHL season, as a Florida Panther. His dependability is reflected in a healthy plus-14 rating.
"This guy,'' gushes assistant GM Craig Conroy, "is so underrated. People are talking about Backs for the Selke, and rightfully so, but don't forget about Fro.
"He really compliments the other two guys well. Fro may not get a lot of outside attention but everyone in this organization knows what he brings, believe me."
Nowhere, it's safe to say, has coach Glen Gulutzan's defence-translates-into-offence mantra been given more validation than by the 3M Line.
On Friday, Frolik scored a goal, added a helper, hit a post and forced Stars' goaltender Kari Lehtonen into a couple of sharp stops during the Flames' 3-1 trimming of Dallas. Shut off the scoresheet Sunday versus L.A., Frolik nevertheless produced a game-high five shots on goal.
"We put video things together for guys,'' reminded Flames' boss Glen Gulutzan. "I set his to Christmas music, cause he's hit so many posts in the last week, with all the ting-ing going on.
"He's a great pro. Young guys can learn from him - He does the same things diligently, every day. You see it in his game.
"He's there with Gio and other guys like that. You never see their game dip. Sure they have some better than others but they never go below the 80% line. They're always humming about 80.
"He's a real good player for us."
