So are there other requirements and pros/cons you left out? What happens if say you only gave 1 year to every scrubby prospect so you can give 10 years to somebody like Justin Upton?
Honestly, I don't see much point in giving more than whatever minimum required years to the prospects on your list after maybe Lubanski. I guess if you need the pitching help real soon, Penn might be worth a shot w/ a few years. But the rest of your list after him probably doesn't deserve more than the minimum requirement.
Just another amateur learning to paint w/ "the light of the world".
