I personally know several players (none larger than 5'10" or more than 180...most less) who could never afford to play at a PG showcases or on teams that attended PG national events...i made a deal with some coaches to pay a discounted fee to play on a team as guest players...nearly every one of these guys made all tourney team at mult diff events and one of them was all tourney at every event he attended...Including his first tourney where he struck out 16 in his first PG game he ever pitched. Yeah theres a lot of non-prototypical talent out there that flies under the radar...
PG does a fine job though of capturing info to the best of thier ability, and continues to improve methods constantly...continuous improvement is a big word in many corporate enviroments...glad to see PG believes in it too...my son just missed the boat on some of the new metrics that really would have helped him, but little bro (age 1) may have a completely different experience when his time comes!!!
