The follow through Does happen on its own, but we rarely think about it and that is a bad thing.
The point we should actually be focusing our energy on is the point that happens just after the disc leaves our hand. This means that we have focused our energy THROUGH the hit.
Secondly, while the follow through happens on its own, a lot of people are making bad shot shapes and throws because they focus none on their follow through. so this dank noodle is just flappin in the breeze and it doesn't help you.
It's important to direct our follow through on target line to assist in our shot shapes and trajectories.
It's important for us to use good follow through technique as well.
When you purely focus on the hit, youre most likely slowing your arm down before the hit and your follow through is still there, but you just robbed your shot of power.
Also a good example of why follow through focus is important.
One of the issues I see with a lot of players is upshots.
They suck at them, hard suck.
Knee's are sore from sucking so hard suck.
I fix their up shot with 1 instruction.
"Flourish the follow through"
What a majority of players are doing is trying to jerk stop the distance vs swing the disc.
They are worried they are going to throw passed the basket if they dont.
You just swing easy and really focus only on that follow through and NICE, CLEAN, SMOOTH throws happen with TONS of control.
