Betting action is driving the move. Maybe you're referring to bettors? And I think there probably is some Joe Public movement that's happening gradually from the Center injury. But no, sharks know about those things literally the minute they happen. They would have jumped at the 14 point spread immediately if that were it. This late movement likely points to the sharks thinking the line is out of line too high...AND there's likely something we don't know about going on that should benefit IU's chances. Its too sharp and big a swing, for there not to have been some sort of event...I would think. And again, if that event were the C injury, the movement would have been immediate when it happened.
I remember an IU bball game a few years back against Wisconsin at home. Maybe Romeo's year? Anyway, Wisconsin was one of the best teams in the country, and we were average. The line dropped dramatically the last day or two before the game, all the way down to I think an even line maybe. No one really knew why at the time. Ended up that Wisconsin was battling a nasty round of flu virus, and many of their players were impacted by it. We upset them.
These late swings always raise my eyebrows a little bit. Hope it bodes well for IU!
