Anyone who got minutes at PG will train.
Since there are only 48x3 minutes available during a week, the most that can train while getting full training is 3, but if you 8 different guys play PG during the week, they would each get some amount of training. Getting 3 guys to each have 48 minutes at PG is difficult though.
Anyone who played 48 minutes or more at PG will get full training. The guys who didn't reach 48 minutes will get a reduced amount of training.
