As Blackhawks rookie Andrew Shaw skated to the penalty box after a fight Sunday and mugged for a lathered-up United Center crowd, cameras caught an entertained Patrick Kane hanging on the boards with a wide grin interrupted only by his ubiquitous mouthpiece. "I'm sure I'm not the only one that was laughing," Kane said. Nor is it the only Kane-related moment to smile about lately. The scoring touch that eluded the kinetic forward for more than half a season evidently has returned in abundance just in time for the playoffs, with two more goals Sunday continuing his late-season resurgence.
