I agree that this is a good place to start, especially when working with someone with limited experience. That said, I also agree with chrisspots concerning the use of "cookie cutters". It can be too easy to focus on drills and such, and take athleticism away from a developing hitter. I think it is important for a hitting coach to understand the difference between style and sequence. Know what adjustments are needed, and what adjustments could be detrimental. My personal preference is to work with hitters individually. If I spend even 15 minutes with an engaged hitter, I believe we can make some progress. That said, this isn't always possible in a team setting. At a recent V/JV practice, I was asked to work with 16 hitters and I only had 1 hour to do it. This required the use of several stations with tee drills, and myself in a cage throwing front toss. Generally speaking, I am not even a fan of tee drills other than as a warm up, but having 15 hitters standing around while one was in the cage seemed unthinkable to me. Maybe some other coaches are better in that type of team setting, but in my opinion, it limits the overall effectiveness of the instruction. JMO.
I've instructed hitting in a team/group setting and IMO you have to have at least one and maybe 1.5 walk/talk sessions where you really explain drills, what you're trying to accomplish and how to execute drills. Not every hitter may buy into it or even be listening, truthfully, but it sets up some reference points and common language ALL your coaches can use with hitters and some hitters may really buy in from the start and benefit from the details.
