I personally have always liked training players until they are about 23-24 and then decided. With that being said you have to weigh the options of if you want to start fresh with new trainees when your current ones are 21-22 or polish off the older trainees. Feel free to join the USA Buzzerbeater Discord and there are people that can help you out and give you more specifics. Welcome back!
