though I also think 45 is more like a 0.5 WAR player. I wasn't trying to get too fine with the "0 WAR" comment, just trying to describe the type of player. 0.5 WAR is essentially the same to my point. If you want to win the WS, you need a roster full of 2-8 WAR type players. Of course you aren't going to have everyone doing that. And you might live with someone at the 0-2 WAR level for a short period of time. But you should always be trying to replace those type of players (note that bench/BP players' WAR numbers will have a different expectation, but similarly adjusted for PT). Sure, a player that is a 45 can become a 55 and vice versa. That isn't really the point either. Statistically, I would expect you will have a better shot having a 55 in the minors become a 55 in the majors than a 45 becoming a 55. Given the explanation of the risk factors, there are only two factors that concern me for risk: - Injury - Someone close to the bigs without realizing the potential in production. Seems that most guys will be ranked risky due to distance from the MLB level. And while, I understand the need to show that "risk", its really only useful if you are rating one MiLB farm against another. It doesn't represent a true risk since all players need to start at the bottom (just about all of them).
