How about Gatorade?
If they brought it onto the field themselves for hydration purposes. Heck, I did too. And if anyone was taking any “performance enhancers” at home, there’s little I could do about that unless I noticed some (likely negative) trend in a player’s overall demeanor. But I certainly would never have provided it for them.
I was asked about a lot of things (Vietnam fascinated them endlessly), and I always tried to be as forthright as I could with them.
I told them marijuana use at height of their brain development was destructively bad and that if they had to smoke it they should wait until they were twenty-five or so, and then see how they felt about it.
I was proud of them that they at least seemed as close to the straight and narrow as the “typical” modern high school environment would yield.
And they made me fee like a kid again, which at 63, was as great as the rest of it put together.
I’d like to coach again when we move to SC. They’re just about going into eighth grade now. I’ll try hard to be ready.
