I always use older players to help the younger ones to succeed.
Side note:
There are no tutors or chemistry factors in Buzzerbeater, even language means nothing for the players. It won't make any difference thattwo players are together for 10 seasons or one game. Perhaps you knew, but some may not.
PS: I'm 34, and in real life I get drops on my skills any time I step on the court... Trainning would hurt me more ;)
