And thethe just proved he doesen't understand WAR.
WAR adjusts for position. You're confusing offensive position scarcity. The reason why Andruw gets paid more for an .800 OPS in CF than a 1B does for .850. Because of adjusting for the position WAR takes most of that into account. Not perfectly. Last year qualified players, there were 13 1B with a 2 WAR or higher, there were 11 2B. An insignificant difference. The only reason it's easier to find more 2.0 fWAR players at 1B is health. 2B is one of those positions that players often get hurt at so there are usually less qualified 2B.
So if there are more players at one position that meet that threshold then its easier to find players at that position that meet the threshold. Thats pretty standard Zito.
