I'm not sure what is more impressive about Drake. Is it the Bulldogs being 15-0, or having covered each of their 13 lined games? 
None of this is lost on the oddsmaker. They are starting to make bettors lay a tax on the Bulldogs if they want to back them. At least that's the way I see it because this line is several points too high in my view. 
Illinois State should be up for this matchup. The Redbirds were taken out of the Missouri Valley Conference Tournament last March by Drake, losing 75-65. The Redbirds are just 5-10 this season, 2-7 in the Missouri Valley Conference. They have the motivation and scoring to cover this inflated spread. Drake averages 82.5 points a game, which is 18th-best in the nation. Illinois State, though, puts up 74.3 points a game.
