Hmmm, I guess you have a point there, but first they have to earn the right to come up and sit on the bench and wait for some thing to get them in the game, mean while, veterans can stay and play because they have been there, done that, and are not learning how to play or showing they should still be in AAA.
Sano , God bless his soul, showed that some times, AAA is not far enough to teach them some thing a few years back.
