Eric Locke, my cousin (Ronnie Chambers) coached at Cookeville around that time and had sons who played on those Cookeville squads back then. If I'm not mistaken one is your OC.
As far as recruiting, I hate to burst your bubble there but it's fake news. We (Maryville) hear that same crap every year too.... If anything, we've traded players between each other more times than I can count over the years for the simple fact the schools are 5 miles apart. I was a Maryville kid K-12 and most of those Alcoa kids are the same, but there was a time I almost ended up at Alcoa simply because we moved 2 miles across town from East Maryville.
Now do both schools get a few kids from out of the area every so often? Sure, but it's not like it's some massive number of kids or even some superstar athlete getting a job at the Nissan plant in Murfreesboro..... That's probably why Rankin chose to come here in the first place. He essentially plays against teams in his classification worse than the JV squad and doesn't have to worry about bringing kids in like , he had to at Riverdale. Alcoa was already established waaaaaay before Rankin got here and if I'm not mistaken they're the only public school (besides us) that has 4 different head coaches win state championships.
