Huh.. didn't know we were this big of dogs vs Portugal? Guessing the Altidore news plays into this a bit?
USA +290

Portugal is a much better side. I don't think those odds should surprise anyone.

They are rated significantly higher in FIFA and most other rankings.  With all the limitations that entails.
Portugal did not win their UEFA qualifying group (Russia did).  Portugal drew with both Northern Ireland and Israel (twice!) in that group, in games that mattered.  But their world ranking improved from their playoff wins over Sweden and some good pre-WC friendly results (although they did draw Greece without Ronaldo).
Portugal is a better team than the US, assuming Ronaldo is healthy.  Having a player who can single-handedly win a game is always an advantage.  Remove that factor, and Portugal has several players with better pedigrees, but I'm not sure it's a better team considering style and form.
