If you are not looking at advanced stats, and you are not using the eye test (which again doesn't work unless you watched both players play almost all of their games), then how do you know that Howard should not have been in the running?
In terms of traditional thinking, Howard was a beast in HRs, RBIs, and getting his team into the postseason, as Bellhorn posted. He also was a beast during the month of September, batting .352/.422/.852/1.247 , which leaves an impression on voters.
Pujols had the clear advantage in BA and strikeouts, but his team was not playoff bound.
As I posted earlier, I agreed that Pujols should win. However, based on the traditional criteria, there is no way to say that Howard should not have been in the discussion unless you are using advanced stats, the eye test, which you can't, or basing that opinion on reputation.
BTW, thank you for making the point for me about how traditional views are so often so very wrong.
