Re: What makes a good minor league system?
It would seem to me that luck wouldn't be a factor in scoring the strength of a farm system. While it definitely has a hand (probably the most determining factor of them all), it's not something that can be controlled by the organization. As a matter of fact, the organization is trying to control the other seven (or eight, if counting the one added after Laxtonto's initial post) factors in order to help your farm's luck out. For the most part, if you look at the odds of a draftee making it to the big team, it seems like bad luck is the overall theme of developing your own talent.
Creating a rating system shouldn't take into account luck, because if a club is doing most of the other things right, luck is more than likely going to be on their side. That doesn't mean luck shouldn't be discounted entirely, in that if a farm system is still failing although they seem to be doing everything right then if all other explanations are exhausted then you still have bad luck. Just one lurker's opinion, though.
