I wouldn't say Flip's line was ever worse than Modano's. Fewer points in the past few games, but points aren't everything.
The BFF combo was the team's best line for the first four games. That's it. Flip's lack of production over the past six games before tonight illustrates that. If it were the team's "best" line he'd have been producing. Bertuzzi and Franzen each had three in six coming in, for seven total between the three. I would say Flip's line has been the third best since Abdelkader came back. Tonight the Franzen/Flip/Huds line might have been the best line out, but the past few games Franzen, Flip, and Bert together have been performing worse than DZH or the Modano line.
The BFF line was our best for the first four games. They were also close the first few games after Mule sat out the one game. The HFF line was arguably our best tonight. That says alot when we have a line featuring Datsyuk and Zetterberg. Also says a lot that before tonight, when he wasn't a healthy scratch, Hudler was a part of worst line pretty much every game.
Hudler hasn't been good this season, no matter how much you want to blame it all on Cleary and Modano, there's a reason Hudler sat out two games. Filppula has been very good, no matter how much you want to give all the credit to Bert and Mule, there's a reason he gets tons of ice time.
