Chemistry is as mysterious in hockey as it is in the laboratory.
But Chicago's Dave Bolland sees the right ingredients in the line he'll center with Bryan Bickell and Michael Frolik in Thursday's fourth game of the Blackhawks' Western Conference Quarterfinal series with Phoenix.
That's understandable. Frolik, subbing for the suspended Andrew Shaw, scored one of Chicago's two goals in the 3-2 overtime loss in Game 3.
"Bicksie and Fro, we played together last year. This year we had some time together," Bolland said. "We all know what Fro's all about. He's fast, he's got a great shot, a little bit of that Martin Havlat in him, that speed going down the wing. Coming out of our own end, if I throw him the puck, I'm sure it's getting out of our zone."
On the outside, it appears Frolik's speed makes up for Shaw's grit. But Bolland believes Frolik can handle the tough stuff as well.
"He gets in the corner, gets dirty," Bolland said of Frolik, three inches taller and 18 pounds heavier than Shaw. "We use them the same way, but they're different players."
What Frolik wasn't during the season was productive. He scored only five goals and 15 points, and was a minus-10 in 63 games, the reason he was a healthy scratch in 17 of the last 33 regular-season games, and the first two games of the series. The last 10 regular-season scratches came after Shaw was recalled for good from Rockford.
