My son (I hate referring to him as "my 2019" because it makes me feel like he was created in a petri dish and I am a caretaker) just went to the PG West National Underclass. Awesome event ran very professionally by the PG staff. The event ran like clockwork and drew in some quality players. I would venture to say this event (since it is in December) was smaller in the number of players it attracted and therefore the caliber of players may also not have been as high as at the summer PG showcases. Lots of younger players (2020s and even a 2021). No college coaches in attendance that stood out because it is the Quiet Period, and that is exactly why I chose this as my son's first PG showcase, no stress (yeah, right) and we could see where he stood amongst his peers. Now that it is over, we know where we need to focus on for the future.
Highly recommend these events.
