I don't mind you asking!
I logged games for them from 05-07, but ended up getting a "real" job elsewhere, which turned out to be a mistake as they've grown so much since I left!
To get my foot in the door I was a level 1, which meant I would only break up when a possession started and stopped and passed it along. Then (level 2) I would identify who was on the court for each possession. Then I started logging the outcome of each possession. After that I started to identify and tag actions that teams ran. The cool part was I could see any game in real time and/or rewatch games using their query features. For example, I could go back and watch a Blazer game, but only the clips where we scored, or clips where Telfair had an assist.
Having played and coached up to that point, I was blown back by how many assumptions and passed down theories about the game I believed that were not backed by data. Kinda humbling.
You're 100% accurate that those countless hours and the data I saw has influenced what I think really matters. Just to be fair to anyone who is reading my posts for the first time: I don't think coaching is worthless and has zero impact, I just think it has a much lesser impact than most people here.
