Might be a bit of a stretch for this thread, but I played basketball in Chattanooga, and we won state my sophomore year primarily because of two guys that were absolute beasts at the high school level. One of those guys was Jason Holwerda, who went on to start for some very solid Vandy teams that made at least one deep run in the NCAA Tournament. He was a senior that year, and his dad was the Superintendent of the small school we went to, while my dad was the shop teacher. Even though he was two years older than me, we grew up together, and spent summers working landscaping together at the school, and going to the gym when we finished for the day to practice. Spent a lot of time practicing throwing him alley-oops, mainly for fun, but also because he could jump out of the gym and we thought it could come in handy the following season. Anyway, we were playing Red Bank in a non-district game (they were AAA, largest division in TSSAA basketball at the time, and we were A, the smallest division) at home one night. Gerald Riggs, Jr. was sitting in the front row with some of his friends, as a lot of people came to watch us play because Jason and another guy named Martin would regularly posterize opponents and made us fun to watch. At one point in the second half of what was a close game at the time, Jason was on the opposite wing from where I was, and I had the ball. He faked a cut toward me, which the defender bit on, and went back door along the baseline. All of the time we spent messing around in the summers paid off, as we caught each others eyes for a split second right when he started towards the hoop, and from about 5 feet from behind the 3 point line I threw him an alley-oop. Quite frankly, I threw a horrible pass, throwing it above the square on the backboard. Fortunately, Jason went up and somehow caught it, bringing it down two-handed on the poor soul who came from the weak side and tried to jump and break it up. It was the most amazing thing I've ever seen in a high school game. When he threw it down the entire gym erupted, including Riggs, who was so fired up he ran onto the court and high-fived Jason as he came back down the court to play defense. Sorry for the long post with what I'm sure is entirely too much detail and background, but I'd never before or since seen someone run onto the court to high-five someone before, and I thought it was crazy that it was someone who went to the school we were playing against. After that play, we basically ran Red Bank out of the gym.
On a side note, I've never seen someone who looked more like a man amongst boys in high school football than Riggs did that year. He would truck people, pads popping louder than I've ever heard, and then yell smack talk to the other team so loud that you could hear it from the top of the bleachers. So fun to watch, and I've never seen a RB take so many defenders out of games by lowering their shoulder on them like he did.
