Agressive 2-1-2 forecheck and pinching. Pulling forwards out of position to make quick transition breakout plays so that they can play safeguard instead as well as block shots. Torts' system de-emphasizes play in the neutral zone in order to emphasize play in the offensive and defensive zones. This might have worked in the dead puck era when clutching/grabbing/two-line pass offsides would have slowed down play through the neutral zone but his system is a bad match for today's game where possibilities in the neutral zone are more threatening.
You see it when the forecheck/pinching is ineffective in either turning the puck over or slowing down the breakout: easy controlled entry into our own zone and odd man chances against. I have no qualms with aggressive pinching. I think this team should play that way. The 2-1-2 on the other hand has been effective against some teams and god awful against others. The teams CORSI is down from last year so I'm not sold on it's ability to retrieve/turn over more pucks than playing a 1-2-2 and trying to cause more turnovers in the neutral zone. It could also be that AV's system had them breaking out more effectively so I'm kind of ambivalent about the forecheck.
So CORSI is down, FENWICK is up. I attribute this mostly to defensive zone play. FENWICK is up because the team is blocking more shots and playing safeguard. CORSI is down because the team is too busy blocking shots and playing safeguard to set up quick breakouts.
