I know a lot of people say this on position scarcity but you have to look at it wholisticly, take say Vlad Guerrero and Bobby Crosby, add there stats, it will be better than taking Miguel Tejada and adding the stats of an outfielder from the same round as Crosby. Tejeda is better than crosby but tejeda doesn't get enough stats to make up for how much better Vlad is than the other outfielder. (in general, exceptions are like soriano's 38/41 season which compares with vlads numbers well, in general a position scarce player won't match up favorably enough with a position rich player)
Position scarcity is real. I'm not sure why people disbelieve. Using Mock Draft II as a guide, Crosby was taken in the 12th round. The only OF taken in the 12th round was Brad Wilkerson.
Further, using rotochamps projections (everyone seems to agree they are good) as a second guide we will pit Vlad/Crosby versus Tejada/Wilkerson:
Vlad/Crosby - 1155 ABs, .297 AVG, 69 HR, 195 runs, 192 RBI, 23 SB
Tejada/Wilks - 1191 ABs, .294 AVG, 68 HR, 207 runs, 207 RBI, 18 SB.
What we end up with is a statistical tie, but realisitcally the numbers give the advantage to Tejada and Wilks. Vlads side had a better AVG, but less ABs = tie. Vlads SB advantage is equal to Tejada's runs advantage. Then you are left with a 1 HR advantage for Vlad and a 15 RBI advantage for Tejada. Umm, position scarcity is a sham, is it?
