I think all the griping about Nuge not scoring more goals is misplaced, I've seen him get multiple good looks on net and multiple quality shots that were certainly of a caliber where they had a good chance at beating a goalie, sometimes they hit iron and sometimes the goalie made a terrific save. I always think you should keep career shooting percentage in mind when ragging on a player when they get cold or pumping up a player on a hot streak, most revert to the norm and in the cases it doesn't catch up to them in the current season it will probably happen in the next (kinda seems like that's happening to Chiasson and Neal now).
The legitimate concern at the moment is how ineffective the 2nd line has been at 5 on 5, they just aren't generating quality looks with any real regularity and Nuge has 2 even strength points in 12 games. While Nuge did have brief success with Pouliot and Eberle playing as more of a rush line, I don't think rush style offense has ever been the strong suit of his game. Nuge is a support offensive player, like a Brendan Morrison or a Shawn Horcoff, he doesn't challenge guys and force defensive breakdowns in the same way a Connor, Drai, or Hall would, he's just out there trying to play low mistake hockey (waiting for breaks instead of creating his breaks), he's smart enough to capitalize on a breakdown when it occurs and skilled enough to make a good play when it presents itself, but when his line is easy to neutralize and they aren't forcing the defense into the kind of tough decisions that creates breakdowns he really doesn't accomplish much out there. At present the 2nd line needs to either get better at prolonged shifts in the offensive zone, the more in-zone time the more likely breakdowns are to occur, especially when guys get tired or we need to add a dynamic offensive element who will try to make things happen. I've been pretty against Ho-Sang in the past, but right now I'd consider him cause we just need some offensive spark and I'm willing to take on some defensive shortcomings/character flaws to get it.
I don't think there is anything wrong with Nuge and I don't want to get rid of him, we just lack the pieces necessary to draw the best out of him, it's like a soup where the you have some good ingredients, but are lacking that element to bring it all together.
