I have a completely different take than a lot of these comments. A good assistant coach should WANT to complete the vision of the head coach, whatever that is. Vertical alignment is the way we get better. It is the right thing for kids and coaches alike. One of the ways that a program gets better over the years is that the varsity is not having to learn your major scheme (we are Run & Jump/No Middle Man on defense and 4 around 1 Drive and Space). I don't have to install Rose series, or Predictable Rotations on D every single year because I inherit kids that know EXACTLY what we do. That frees up more practice time than years prior and allows us to either shoot more or add complexity (quick hitters, different alignments, etc.) Its the marathon mindset. Everyone has to be on board. A varsity coach should be inheriting kids that have the prerequisite skills and knowledge to thrive in their system.
