The public is on Detroit (79% on Wagerline on Det +1). If there's no resistance to the public money flowing in on one side, the books (usually) move their lines to compensate. See CHI/OAK for evidence of this public-heavy line moving.

Since the line isn't moving it means one of these things:

1) The books are balanced by non-public money from somewhere else (sharps betting large amounts).
2) The books are actively taking a position on Arizona because they think it's the right side.
3) Wagerline's stats are crap

The top two possibilities above make me think that the books believe Arizona is the right side here, although obviously nothing's guaranteed. Even if I'm right and this is a good play, it will lose 45-46% of the time.

EDIT: On top of this, Pinny shades their line even further to +105/-113, inviting Detroit money even more. Again, Pinny is wrong sometimes, but I like going with these pro-Pinny/anti-public plays.
