Lupul looked like he was really pressing the offense and trying to score after he hit that post in the first period. Give him credit for trying to create something out there, but when you're going at 100% up the ice and 50% coming back that creates a lot of problems.
That's about as good a description of his play as I've heard, but I have even more of a problem with his braincramps in his own zone than his lack of effort on the backcheck.
The Islanders' tying goal the other night wasn't directly a result of what Lupul did, but the puck may have been easily cleared out of the zone before the Isles ever even got that chance if Lupul had stayed in position. My dead dog could've figured out when Clarkson took the puck to the quiet area behind the net that he was going to put it up the boards, so why Lupul drifted away from the hash marks towards the point, only to loop back through the middle and leave his entire side of the ice open, I really can't wrap my head around.
I mean, sometimes when a guy makes a mistake, you can at least re-watch what happened and understand why he might've misread it that way, but Lupul has this annoying propensity for inexcusable 'wtf?' plays in his own end.
