Obviously it helps when we see a player at our events, but it is not neccessary in order to get ranked.
A large number of the very best players do attend PG events. (34 1st rounders and close to 800 draft picks over the last two years) That may make it look like a player has to attend. Many are ranked before they ever attend PG events. Obviously we try to get those prospects to our stuff.
All that's required to make the list is to be very talented and that we see that somewhere.
