So what to make of a line that has the 1-4 team favored over a 5-1 team, albeit by the margin of home field (in other words, it would be a toss-up at a neutral site)?
UAB may be the hardest team in America to figure out. They lost to Florida Atlantic, perhaps the worst team in the Sun Belt; they beat Troy, perhaps the best team in the Sun Belt; they lost to Tennessee in overtime in a game they probably should have won. They were soundly beaten by a good SMU team and blown off the field by a good Central Florida team.
I view this line as the gamblers throwing their hands up in the air, saying 'I have no idea' and giving UAB the standard edge for home field.
