Oregon St over-valued and over-ranked at this point in the season.
Wisconsin sucks and has an incapable QB so that win is much less impressive than it looked at the time (Ranked #13 at the time, no unranked)
UCLA had one lucky win at home against a pretty average Nebraska team, they are still unproven. So Oregon St's 2 wins are really nothing to write home about
Oregon St had a preseason O/U of 4.5 wins, they aren't the 18th best team in the nation
The score doesn't show it but Arizona played Oregon tough in Autzen last week
Letdown game for Oregon St here, take advantage of the inflated perception of this team. Arizona -2.5
