Another fishy line to me is Bucky -5, they are not playing well, lost 4 out of last 5, I'm aware of their home record, but it seems irrelevant at this point. As a UW fan I hope I'm wrong, but I'm playing the Hoosiers.GL to you.
The BC line does feel like a trap but then again the general public may just like the points at home with wake.
The UW/IU line seems about right. Indiana isn't playing the best ball and if they had won more than 1 out of their last 4 the line would be different. I think this is a "two underperforming lets go with homecourt advantage spread". That's not to say that Indiana with the points isn't the pick, but that it is the right line for the public.
