As was said, Vegas doesn't make the line on their own. They pay attention to public perception of a team and adjust the line to manipulate how they hope bets will be placed. The fact that they had to drop the line to lure more UT's way, tells me they like WKU in this game . Some bookies make their living on reverse psychology, but this is the best metric you can hope for in an unpredictable sport.
the odds makers adjust the lines but its an ultimate indicator of what people are betting...people went hard wku to cover....so they dialed it back no big deal
What the Pointspread Represents:
Before engaging in methods to help you beat the pointspread, it is important that you understand the pointspread and what it represents. Most people view the pointspread (or line) as the predicted margin of victory of one team over another. In fact, that is not the case. The job of an oddsmaker is to get half of the wagered money on one side and the other half wagered on the other side. By splitting the bets, with 50% of the money being wagered on each team, the house is guaranteed of making money.
The odds in sports betting wagers that utilize a pointspread are 11 to 10, meaning that a gambler must risk $11 on a losing bet to profit $10 for a winning wager. In other words, there is an extra 10% that must be paid on losing bets. Thus, if the oddsmaker sets a pointspread that splits the money, he uses the loser's money to pay off the winners and has an extra 10% of the loser's money as a profit. So, the job of the oddsmaker is not to predict the margin of victory between two teams and use that as the pointspread, but instead to set a pointspread that will split the money wagered on a game
Understanding how/why lines are set, it's uncanny how often the line ends up being right on the money as far as the final score goes.
Their motivations are to draw more bettors to bet on UT. WKU has a lot of hype right now and has always been considered a great coach (fat bettter than he is but that's neither here nor there) -- public perception is what set betting lines. The goal is always to even out bets and UT has received little hype and hardly a word about the good things that came out of the opener regardless of opponent

Then there's the fact that winning at NCAAF gambling is the least likely sport to win against the house. Oddsmakers know that NCAAF gambling, unlike other sports betting, shows a high degree of team loyalty based betting and they manipulate things accordingly.
Even in academic studies designed to prove market efficiency, it's noted that college football is the exception.
