“Art of the Undercut”
My U16 team played against a team from Pittsburgh that thoroughly impressed me. What did they do?
Undercut our shift length. All. Game. Long.

Undercutting = racing strategy where a car pits for fresh tires earlier than their rival to gain a performance advantage from fresh tires
Those faster lap times then allow the car to pass their rival when their rival eventually pits

Chart from Micah Blake McCurdy
- Shots for + against over time, based on shift start location
What do we learn?
- First 15 seconds account for abnormally high shot rates
- 15 to 40 seconds there is an equal share of shots
- Beyond 40 seconds = getting caved in defensively

Moral of the story & chart:
There is a massive competitive advantage by changing in 40 seconds and under
There is a massive performance degradation that quickly leads to ‘shots-against‘ increasing significantly while ‘shots-for’ decrease significantly
