Respectfully, I think you may be overestimating the value of eybl play as an evaluating tool. Certainly, it is a factor to consider, and a reasonably important one at that, but there are all sorts of examples of guys playing much better or much worse in the eybl setting than they do at the high school level, or at the college level--just in terms of recent Michigan recruits, Carlton Brundidge and Kam Chatman showed much better in eybl than elsewhere, and MAAR showed much worse. The coaching is different, the style of play, especially on defense, is different, the amount of attention to fundamentals is different, the roster composition is often different, forcing kids into roles they might not play as well, etc. Again, this is NOT to say that eybl isn't important--it is--just that it's not a be all and end all. Watching a kid play high school ball, with kids and a system he plays with on a season long basis is very important as well.
