Fair enough - I guess then you have to ask yourself if you practice the kid in red's swing enough what would you be left with? Do you believe that game conditions would change what you practice? Would a kid that takes a lot of swings squishing the bug then not do it in a game?
Butter,
I know you mean well also but, one is a game swing the other is a practice/drill swing. One hitter is swinging at a real ball the other hitter at a wiffle ball. I believe also the ball is at a different location and speed.
Is that the 'spinning' thing again? The hitter in red doing a drill swing is also 'squishing the bug' as you see it?
