You forgot the torches - you can't have a proper peasant revolt without the torches!Holy God! Every one of you should just bring pick axes and pitch forks and tell the college coach(es) how bad they are...thanks for the comedic relief!
Go to a Dave Hudgens hitting clinic sometime and you will start with hitting ground balls off a tee to a spot 8 feet off the tee...I know...the internet heroes here know more than a hitting coach who has been in MLB for 30 years...there is value here if you are interested in learning to turn the barrel against a firm front side, creating a corner with you body and creating a barrel path that has a corner too...again internet heroes know better <SMH>
I don't think anyone here would really argue against that drill - b/c there's a good chance of the drills purpose (as RDB posted) being explained to us beforehand.
So what would I consider quality hitting instruction?
There is no doubt the Hansen principle has to play into this but at the end of the day results have to count for something...quality hitting instruction can be boiled down to whether you can answer these 4 questions in a positive fashion: 1) Can the instructor effectively change the movement pattern? 2) Can the instructor communicate with your DD in a manner in which she understands? 3) Do you see changes in their swing and 4) are they seeing positive results in games?
Putting on a nit-picking hat for this one - but might #3 be an "optional" question? Either due to such a minute change you don't really notice it, or a more likely scenario (and probably only applicable to (guessing here...) 12YO and above) where the change is mental, e.g. timing, or just a coach that does #2 so well, the increased confidence makes the current mechanics remarkably more effective.
Returning to Hudgens vs. the example given by the OP, I'd summarize it by saying it's the difference between:
a. hitting ground balls to learn how to do "x"; and
b. learning to hit ground balls
