BBALLCARES - it is really easy to second guess every step along the journey. If he indeed did get stronger, gained weight & improved his hitting over the summer that might have been the best thing for him...
The live at bats and scout attention are great in the summer, too, of course, but a summer schedule can wear a catcher down. Probably best to trust the coaching staff. If the school plays a competitive schedule, he'll get seen in both the Fall & Spring...
