IUPUI was a 2 pt favorite when they played earlier, so Detroit will probably be a 1.5 to 2 pt favorite at home.
Detroit was actually favored earlier this year against Eastern Mich and Ball St, but that was 11 or so losses ago.
They both are terrible against the spread, and have been for the last 4 years. If you have the urge to throw some $ on it, flip a coin and then DM me for the gambling addiction hotline # :)
