I wouldn’t characterize Keefe hockey as rush based at all actually. It’s more like he treats the puck too preciously and values holding it and avoiding going in clean north south lanes where you could lose the puck. Which results in regroups, sluggish movement and overthink, and avoiding going to areas where there’s confrontation. At its worst it enables guys like Engvall, Holl, Kerfoot etc who have no business holding the puck too long into making risky retreats. Basically conceding a lot of the good attacking ice and taking the puck to areas prone to counter attack, which is why the defensive breakdowns always felt so catastrophic when they occurred. It’s like Pep Guardiola soccer applied to the wrong sport.
