That's true, but the relationship between value and performance is hardly linear. To put it in a practical application, I find dollar value in auction leagues to be a numerical assignment for a player's value. Just because Markakis is worth $22 (2008 AAV) and Jones is worth $1 doesn't mean Markakis is expected to finish the year 22 times better than Jones. As a player's stats move further above the mean performance, the standard deviations become more valuable. That's why the price of ARod is more than twice the price of say, Garrett Atkins despite the fact that ARod won't put up twice the statistics of Atkins.
