I noticed this morning that while all the other shops were steaming heavy on Michigan State and moving the line up to 4/4.5/5, Pinnacle was holding 3.5 and juicing the hell out of it.

Personally I think MSU should be able to pull it out but these line movements are generally an indication of Pinnacle taking a stance on a game and collecting juice from heavy action on the other side. It's usually best to go the other way so Iowa +5 looks like a good play. Michigan State probably wins the game by one possession. At the very least, I think MSU -5 is a losing ticket.
Good luck.
