For all that Dumba and Goli were on for all four goals, i can't find fault with them for any but maybe one goal.
First one JEE lost faceoff, Dman never had a chance to touch the puck, and covered reasonably well, forwards at fault.
Second, Kap lost puck by net leading to quick turnover- Kap, and mainly Fleury, at fault.
Third, Dumba was at fault, Goli did his job. Dumba coasted back to front of net. If he had hustled, he would've been there to cover goal scorer.
Fourth...more of a team breakdown. It seemed like it was Dewar, but really, if you like at it, Petan (defensive play is not one of his gifts)breaks down towards the goal line for no apparent reason rather than follow the play and clog up the slot, where he should have been.
BTW, Petan should NOT be in a defensive role. He should be playing with Boldy/Kap/Zucc, or not at all. He is an offensive player, for all that his NHL production is pretty lame.
