You could also say that the +/- is the Nemeth factor that made even Igor play like shit and lead to EN goals against boosting the minus side.
Your argument goes along the line of Kakko "doing nothing", people being depressed about the kids based on "other team's fans" calling them busts etc. Right.
That would assume that all of Nemeth’s - came while the kid line was on the ice, which we know not to be the case. Trying to pass it off on Nemeth just because their numbers match is disingenuous. The kid’s line has allowed twice as many goals against as they’ve produced.
