Postseason play in college basketball remains one of the greatest spectacles in all of sports. Year in and year out, the NCAA Tournament gives us shocking upsets and storylines. But no year in recent memory can compare to this as the highest seed total ever to reach the Sweet 16 since the field expanded in 1986. Four double-digit seeds are still alive and that doesn't even include darling Loyola Chicago.

Oddsmakers seem to think there are some close games coming up as well. Only two teams, Arkansas and Gonzaga, are double-digit favorites. The Razorbacks are facing No. 15 seed Oral Roberts while the Zags get No. 5 seed Creighton. Meanwhile, No. 1 seed Michigan and No. 6 seed USC are the smallest favorites on the board as they take on Florida State and Oregon, respectively.

Even after all the madness of the first and second rounds, there's still plenty more to come. And you'll want to be on top of all the upset specials and chalky favorites ahead of Saturday and Sunday's Sweet 16 action. Check out the lines below from William Hill Sportsbook.
