Ortiz should still be considered(which is in the title of the article, but I don't know if he used those words himself). I've always said that MVP voters place far too much emphasis on the success of the team. Value is value.
As for the DH thing, bias or no bias, Ortiz was not the best hitter in the AL in '05, not by nearly any standard. A-Rod had more batting win shares, a higher OPS, a better EqA, a batting average and on base percentage 20 points greater, more home runs, more total bases, and more runs created, and that's before you adjust for the fact that Ortiz plays in a hitters park(while Yankee Stadium isn't kind to righties). Alex Rodriguez was the best hitter in the AL, and should have been named MVP, even if he never put on a glove. That he did only distanced him further from Ortiz(as did his 21 stolen bases). If Jeter had put up those numbers, nobody would have even considered Ortiz. Instead of inventing ways of discrediting him by referencing obscure, random stats, they'd come up with new ways in which he makes everybody better. "Jeter's hair is perfectly aerodynamic", "Jeter always picks up the tab at restaurants", "Jeter reads Gary Sheffield bedtime stories and tucks him in at night", etc.
Really, the first, last, and only full-time DH to deserve the MVP was Edgar Martinez in 1995, who lost the award to another loudmouthed Red Sox slugging fatass, Mo Vaughn.
