I don't think this is an issue of BIAS, this is a legitimate argument. But I'm glad to know that you're capable to taking a non-biased point of view, while the rest of us are completely biased and subjective.
If you took A-Rod out of the lineup you would be taking out the only consistent player on that team? Are you kidding me? Jeter is hitting over .300 with over 100 runs. Sheffield has 102 RBI. Giambi leads the league in OBP. Matsui has 110 RBI. So A-Rod has done well all year... so what? You said that Manny, Varitek and Mueller are having very solid seasons... are their seasons MORE solid than, say, Sheffield, Giambi and Matsui? Look at the numbers, obviously not. Tek has had a great year, as has manny but look at RBI's, HR's, OBP and OPS. There is little difference at all, if any it favors the Yankees.
I'm so sick of all these "poor Yankee" arguments about A-Rod. The fact of the matter is this: The yankees have had a disappointing year. They could have had the same disappointing year if you put Bill Mueller at 3rd for them. They haven't been hurt by their offense (currently they are 2nd in Average, 3rd in Runs, 3rd in hits, 3rd in total bases, 2nd in Home runs and 3rd in RBI. Not to mention the fact that they are 2nd in walks, 3rd in Slugging and 2nd in OBP). So don't give me the argument that without A-Rod the Yankees would be a weak offensive team. Maybe CONSISTENCY isn't their strength. Giambi sucks this week? That's okay, Matsui is hot. Jeter struggling? Okay, Sheffield is on fire.
I'm not saying that Ortiz should necessarily win the MVP. A-Rod is extremely deserving and if he wins I won't be disappointed. However, Ortiz has done everything possible to win the award. He has knocked in more runs than A-Rod, the same number of HR's. He comes through in the clutch and, yes, like you said, an RBI in the 1st is, in theory, as valuable as one in the 9th, or 10th. But if you're at home and hit a walk-off home run, that run is not one that the opposing team has a chance to make up later in the game. They can't bunt a runner over, they can't sacrifice, or squeeze or anything. It is an exclamination point and a nail in the coffin.
Finally, and this has little to do with the voting but A LOT to do with value:
Ortiz: $5,250,000
A-Rod: $25,705,118
Now, if your argument is that A-Rod is better because of his FIELDING, then my argument is: do you think you could get equal or better fielding for the remaining 20,545,118 dollars difference? I think you probably could get someone who would be as effective in the field for that amount of money. if I were starting a team I would EASILY choose Ortiz over A-Rod, knowing that with the remaining 20 million dollars not only would I get the same offensive output, but I could easily make up the difference in fielding, while ALSO adding some value offensively.
The sox are a more balanced team, but the only reason they can be balanced is because they have Ortiz and Manny. The yankees are a top heavy team, Jeter, Rod, Sheffield, Matsui and Giambi have carried them this year (in varied forms).
So, again, A-Rod is deserving. Ortiz is deserving. I don't much care who wins, but don't pretend that the Yankees would not be anywhere without A-rod. Look at the stats first.. Look at the RBI's, and the HR's, the OBP and the Runs scored and then come back and say that it has been ALL A-Rod to the same degree that the Sox have been ALL ortiz. Offensively, at least, Ortiz is more valuable.
