Hockey game systems and hockey set ups like 2-2-1, 1-2-2, 1-3-1 and 2-1-2 are basically only visible when the hockey team has lost the puck and changed from attack to defense, or are just changing from defense to attack, that will say in a fast counter attack in a hockey game.
I will add a few examples of the different hockey set ups, such as 2-2-1, 1-2-2, 1-3-1 and 2-1-2. The set ups can be played in many ways, for example, offensive, defensive, and right or the left-weighted.
Systems can also vary depending on the hockey team, coaches, players, their competence or skills level and their given roles, so for an example a 2-2-1 hockey set up found on this page does not need to be the same as how all hockey teams and coaches will play the 2-2-1 set up, these are just my examples.
Images are marked with green areas, the plan is to win the puck primary in that area. Red areas represent dangerous or game system / design / set up weaknesses.
I will also add various openings / break outs in hockey, or the small golden details which will help you break the different hockey systems, if you can’t wait you can purchase the drills 😉
