A long time ago … a very long time ago, I filled in with a 17U club as a favor. I ran into the exact situation that you mentioned here.
The attention span seem to be the key to everything. If the interest was there - fine. If it wasn’t - boring! zzzzzzzzzzzzzzzzzzzz
My Mrs came up with the idea of involving the more talented members of the club with the coaching process. Not taking over in places that these guys had little or no experience in, but integrating the practice and game experience USING those with more depth and talent to help the others who were less so.
It took me a while to fiddle around and work all the bugs out, but after three weeks of pratice sessions I had a club firing on all cylinders.
At the start, I told the gifted guys that I was depending on them to bring this club together … better with them than just me alone. I built up there confidence by recognizing each player for his outstanding ability in one way or the other. I then placed all the gifted infielders on the skins, gave the catchers the infield pratice balls and told them to give-it-a-go. The infield practice went smooth and some lasting friendships were in the works. " Let’s turn two on the next one"… I’d hear, then I ask each top roster player to explain why … how did he set himself up for this play … what was his prep work… etc, to the developing players next to him.
When things really got going, I’d designate one player as the field captain during a practice, then switch to a different player for the next. I’d step back with my backstops and we’d talk about what we were seeing. I wish I had some assistant coaches - but things being what they were, I was lucky to have what I had.
By the way, I didn’t have one pitcher on the roster - not one. So, I took eleven players at random, shook their hand and congratualted them on being “instant pitchers delux” - welcome! Needless to say we weren’t overrun with scouts that year, but we did have one heck of a batting order. Funny how a pitching coach can be credited with improving the batting prowess of a lot of guys who where just born to swing a bat. (Personally - I didn’t have the foggyest idea. But that’s a story for another time.)
