I was having this conversation with a friend earlier in the day about this. Who would you put your money on as being better in their team controlled years (let's just say better WAR during their first 6 years as a major leaguer)?
On the one hand Jacob Turner is a much more heralded prospect who has breezed through the minors and is pitching well in AA at a young age. On the other hand Brandon Beachy breezed through the minors as well(albeit with worse age vs. league due to being a college guy), but mostly as a reliever. But he's performing exceedingly well in his first full season as a starter, in the majors nonetheless.
So what do you guys think?
