Bad goaltending - YesWhich of these are untrue?
Bad defense - so-so defense. With the addition of Miller, I'd say it's improved.
Half the roster underperforming - Kreider and Zibanejad are underperforming. Some are overperforming. This is similar to most every team.
A terrible system. - Based on what? I mean, exactly.
A clueless coach - Same as most every other coach.
And a roster that clearly doesnt want to play for said clueless coach - this one you just made up unless you're in the locker room.
