I have a son going to a Catholic school next year. He's on an Express team but not the A team. Do these B team kids sit the bench or are they getting playing time at the Catholic schools?
At Chaminade, except for games against Darien / St. Anthony's, etc., for the JV-B (freshman) team it usually works like this -
Starters (top two middie lines) - first half
Second group - third quarter
Third/fourth groups - split the fourth quarter
There will be movement within these groups based on injuries, performance, etc. If your boy ends up in one of the first two groups by the end of the season, he will probably be invited to Express A next summer as the roster grows to 30.
