Another factor is what the little voice in a player's head called " agent" is telling them about a career transition from starter to reliever early in their MiLB-MLB journey.
I'd much prefer buying tickets to see if the young players can find their way or flame out at the MLB level then buy tickets to see Margot-DeScalf level MLB veterans play.
I will never understand how people who have been playing baseball since little league can reach the highest level of the game and not know where to throw the ball in every situation.
