Johansson had possession of the puck before entering the zone and it shouldn't have been a question of whether or not the puck/skate was over the line first. If anything, it should be challenged whether or not he had possession.

In the replays, his skate looked like it was above the blue line before the puck crossed the line. So, if that's what they would call offside, I'd have to grudgingly agree.

I still consider Johansson to be in control of the puck while entering the zone and he would be allowed to precede the puck on the play. He had control of the puck from the red line and tried to deke the defender at the line. He should be considered in possession of the puck..
