@LVeinbergs said "From my experience, the data most valuable to coaches when recruiting is the basics: EV, Distance, bat speed (maybe), some game stats, and video."
I'd largely agree with all this. Your problem is all this information is already available and through any number of organizations/avenues. I am all for ideas and innovation (and dreaming big), but I don't like your chances in the slightest in getting anywhere with this. Are PG, PBR, etc all perfectly standardized? Nope. But they're close enough to give coaches what they need initially in order to put most kids into their yes, no or maybe piles. If a kid attended 3 PBR showcases and his exit velos were consistently above 97 mph (or whatever), then that's either enough for a particular coach or it isn't. For some that 97 mph means a kid immediately gets into the yes pile, but for others, it's the maybe pile. But once they feel a kid is a yes or a maybe, the coaches/scouts will take it from there. I'd argue that once a player meets a certain threshold for a coach, PBR and the like are no longer part of the equation. PBR/PG metrics are an easy to start whittling down the pool of candidates for a coach. They're not super trustworthy/accurate 100% of the time, but close enough for many when they see a kid has an 81 mph exit velo or whatever. It doesn't matter if that number has a plus or minus 5 mph margin of error due to a bat (wood, metal, illegal), a crappy radar gun, an incompetent administrator, whether it came off a tee or BP, etc.
For your product to beat out what is currently available it'll have to be significantly more accurate, more easily accessible to everyone, cheaper, and adopted coast to coast and everywhere in between. Right now, even the long well-established big dogs aren't universally adopted/implemented/accessible coast to coast. Yes, it's Nebraska, but I live in Omaha which is by far the largest city in the state. PG has zero presence here. You wanna do a PG showcase? It involves a 3-hour drive to Kansas City. We've got two D1 teams in the city and Nebraska is 45 minutes down the road. Perennial Juco powerhouse IWCC is 10 minutes away. We host the College World Series and the Royals' AAA-affiliate plays here. The Omaha metro area is nearing a million people. Yet it is not worth PG's time to do even one showcase a year here. So you're looking at a monumentally huge task and it's one the vast majority aren't starving for a new solution to.
