Once they recovered the puck though the forwards would try to get to the opposing blue line for a tip in to the zone to avoid icing. That was basically their breakout strategy. The other was a chip off the boards.
Both usually led to line changes lol
The breakout once they cleared their zone wasn't so much the problem, it was that they lived in their zone, deep, as the swarm is designed to do, but failed more often for lack of commitment. They just couldn't contain the puck or recover it or they made mistakes that are magnified greatly when 2/3s of the zone is available; that's the risk of the swarm.
The swarm is meant to quickly regain possession by attacking the puck carrier with force (it's like an overload, but more aggressive) whereas a man-to-man collapse is meant to be between the puck and the net, but relies on bigger/stronger defensemen and forwards able to win battles and clear out a large area in front of the net.
The swarm is useful for smaller forwards and mobile defensemen who can/should be able to transition quickly after regaining possession, but require help (sometimes double-pinning) to do so.
Problem is, the Leafs didn't execute very well and as with any system, a lack of commitment is fatal.
5-5-5 to me signifies a higher level strategy for defensive responsibility and puck support/back pressure team-wide. Yes, it's just words right now, but hearing that from a coach with Horachek's background and experience gives me hope.
