The oddsmaker isn't paying enough attention to the current form of these two teams. I guess you can't blame him with this being a Southwest Athletic Conference matchup.
Alabama State has improved its defense holding four of its past five foes to fewer than 69 points a game. Alabama State has a top-50 defense against 3-pointers. 
Texas Southern is just an average scoring team and a terrible 3-point shooting team. If you toss out the Tigers' victory against Mississippi Valley State - one of the worst teams in Division I - they are giving up 72.5 points in their last four games.
