While the Maple Leafs — quite rightly — have to figure out how to get around Zdeno Chara, they do have a trick or two of their own up their sleeves as a means to flummox the Boston Bruins. Randy Carlyle, the Leafs’ ever-thinking coach, plans to mix and match his lines through this Stanley Cup playoff series, which begins Wednesday (7 p.m., CBC). And he’s quite likely going to start off with a line that has rarely been seen: Joffrey Lupul on left wing, Nikolai Kulemin on right and Mikhail Grabovski at centre. “You try to put lines together that you feel are going to give you a chance,” said Carlyle. “It all depends on the opposition you’re playing up against. We want to make sure we’re giving ourselves the right combination and we recognize that Lupul has had a positive impact on every line that he’s gone on and played on.” That means Nazem Kadri and Lupul will be separated. Kadri will be reunited with Matt Frattin and Clarke MacArthur. Both enjoyed what little offensive success they’ve had this year with Kadri as their centre. “We think Nazem Kadri can go to any line and make a contribution,” said Carlyle. “We think Grabovski has a skill set and a level of play that we haven’t been able to touch on yet. We’re going to try and see if we can spread out the offence a little more evenly.” Lupul, indeed, has been powerful winger regardless of his linemates and could re-energize Grabovski, who’s had one of his worst seasons — offensively speaking — this year. “We have the flexibility,” said Carlyle. “We’ve done that all year of keeping two guys together and then moving the third part around as we see fit, based on who we’re going to play against.” The fourth line is expected to be Jay McClement between Leo Komarov and Colton Orr. “We like the reliability,” Carlyle said of that unit. “We like the physical play. We like the ability for them them to chew safe minutes in the opposition zone and force the opposition to play a tougher brand of hockey against them. We’re a team we feel that has to go on the attack. They’ll be part of that.”
