Having a system and implementing it are two different things. Great coaches can implement their system.
The difference between an average boxing coach and a great one isn’t if they know what a good punch looks like, it’s how they teach it, drill it, que it, and motivate the fighter to perform it under stress
I see a 2-2-1 with man coverage in the d zone. But it’s not his system, it’s his ability to coach it.
Players are consistently confused and it’s therefore consistently a mess in the d zone from all 5 men.
That’s why he’s not a good coach.
4 years of practice, video sessions, and roster improvements. The d zone is still absolutely atrocious.
