Every week I look at the upcoming schedule on ESPN to see who is playing and they always list tickets and how much they are going for on vivid seats.com. I like t look at the most expensive and the least expensive. The cheap ones are usually for expected blowouts (VMI vs. Penn State type games) and the most expensive are usually ranked teams or hyped games (LSU vs. Miami, Michigan vs. ND, etc.)

This week the least expensive was $2 tickets to Duke at Northwestern.
The most expensive was APP State vs UNCC at $115.
Next closest were Georgia at South Carolina $107, Clemson @ Texas A&M $101; and Iowa State at Iowa $104.
Shows how hot this ticket is.
