My only response to your points is that ages 21-23 is very different from Francisco's case. He started High A ball at 20 and completed it at 21. Again, he'll be 21 at AA ball until the end of June when he turns 22.
I would doubt that very many players have been as productive as Francisco by age 21 - considering the level of competition. And we all know that the FSL is a pitcher's league.
