• Divide players into two teams (wearing pinnies) composed of an equal number of lefty's & righty's, with lines of players on their proper floor side from both teams spread evenly, in both ends.  One end starts with 4 players from one team (2 lefty/2 righty) in a box formation in their defensive zone, whereas the opposite end starts 3 players (2 Lefty/1 Righty for example) in a triangle formation at centre-floor.
  

• Variation #1 (10 min):  "Down & Back."  The coach starts by sending a pass or loose ball into the defensive zone on the 4 player end of the drill.  These players run a 4-on-3 fast-break against the 3 defenders at centre.  Ideally they finish with a shot, at which point the furthest lefty & righty from the play (communicated) should fall back into an I-formation and defend a 3-on-2 against the 3 defenders that just defended against them (coach or goalie passes a new ball into play). 

• The next rep of the drill should also see 4 players start in the opposite end of the floor, with 3 players in the end that had previously started with 4.  (Draw Diagram)
