One of the largest headaches any coach has, including coaches in the NHL, is their team’s ability to sort out the rush in order to play great defence.
If they can’t, then the attacking team can create chances without having to use much skill at all. Common symptoms are over-backchecking or two players guarding one attacker. It’s a big and very real problem.
Sorting is the ability for defensive players to understand their role on defence and close down the space allowed to that attacking player(s).
The drill starts with defenders in opposite corners with pucks and attackers in the other corners without pucks.
