You don't actually remember them winning any state championship, do you? You just see old plaques at the school? At best you look up past results on a web site?
You would have to be in your early 20's to have actually been there. And that would just be golf, tennis, etc. I have no idea how old you'd have to be to have seen them win @ baseball or basketball. There are no football championships or at least no game scores I could find. btw, where would those scores be posted?
