X's are cycling "up the wall"
O's are cycling "down the wall"
X1 carries puck from below the goal line up the boards to about the hash marks and then moves it down the to X2 who is timing it to leave the line to pick up the puck at or about the goal line. They continue up to the hash marks. X1 has returned to the back of the line.
O1 carries the puck from the top of the circle down ice below the goal line and cycles it back towards the goal line/bottom of the circle where O2 walks down to grab it.
Key is to keep the puck along the yellow dasher. Work on picking it up off the boards.
Don't turn to the middle and 'expose' the puck. Protect it along the wall.
Progression: add in light pressure.
