Looking at Florida vs Michigan I only see 2 possible ways that Florida hangs in there. They NEED to be +2-3 in turnovers(or score on defense) OR get special team TDS. Florida has an inept offense and great defense. Michigan has a solid defense and a normal offense. Harbaugh will find points as the game goes along and could shutout Florida. The fear of Michigan-4 is they could look like they are dominating but you look up and they can`t get ball in the endzone but lead 9-0. You will know one big play and Florida is back in it and could steal the game. There is much more opprotunity for Michigan to cover the 4 in this spot.
