@Master P on my son’s recruiting trips all the college coaches said they liked their pitching recruits to play basketball - helps taller Ps stay athletic. Also, all of those coaches ironically were former HS basketball players and tall themselves.
The point about keeping weight on during all the running of basketball is what concerns me. My son’s basketball coach has them running a ton and he needs to put on weight not lose it.
To help this, his trainer has him taking Creatine and upping the carbs. Hope that helps.
