The LockLeft Course Provides Everything You Need

  • Have you ever struggled with your transition defense?
  • Are you looking for a way to get your team to communicate better on the floor?
  • Does if feel hard to find enough practice time to really improve before your first games?
  • Do you wish your players gave more effort and energy to your defense?

Just like you, I truly wanted to be a great defensive coach, but at every level I ran into these same obstacles. That is why I have spent the last 15 years creating the LockLeft defensive system. I've tried EVERYTHING everyone else is doing. But, honestly, it was a struggle until I finally realized that SIMPLICITY is the ultimate SOPHISTICATION. Simplicity is THE most important thing you should consider before you commit to a system. 

Here's exactly what we'll be covering in this course:

  • How the LockLeft can help your team get to the next level
  • Simple ways to get your team to create turnovers
  • Adversity and how to overcome it
  • How to improve clarity and communication in transition
  • The secret to improving weak defenders
  • Drills and progressions to teach and install the system
