Late response but I see terrible team play. Multiple times a game I see great individual efforts that end up nowhere because teammates are either mispositioned to receive any possible puck movement, usually in the defensive zone, or are changing in the offensive zone. Leaving the zone to cheat defensively or, most importantly, offensively is also an issue doubly compounded when there is no coherent system in place. Sometime I can't even count, because I run out of fingers and toes, how many times a forward wins a puck puck battle but all four of his teammates are already outside the zone to 'defend'. Still get blasted 8-2 or 6-3 somehow.
So properly onto the three things you mentioned, I see compete from a decent amount of players, almost all young. DVO and a few other vets can be fired from a canon though. (Small note: Caufield barely competes but is turning into our version of Ovi so he makes up for it+ elsewhere. Dach.....) Individual decision-making is sorta addressed as best it can be in the first paragraph without going into each individual. Team cohesion would naturally be a consequence of good individual decision-making if a proper system were in place that the players could reference during their sometimes literal split-second decision making.
TL;DR The coach sucks.
