I don't think it means much, really. He got it over Ortiz because (I would hope), he had a far better year on the field and has been, for most of the season, head and shoulders over the rest of the field at his craft. Without him the Broncos aint crap. Without Ortiz its still conceivable that Boston wins it all. Ortiz is really only in the mix because of something that he had nothing to do with and that had nothing whatsoever to do with sports, so it shouldnt really carry any weight in this consideration, IMO.
This is SI (0r the sports version) version of Time's person of the YEAR. Which was the Pope this year.
