After going 8-4 in the regular season each of the past two years, the Gophers could have a difficult time maintaining that success this fall, at least according to Bovada.

The online sports book on Thursday set the over/under for Minnesota's regular season win total at 5.5.

Last year, Bovada set Minnesota's over/under at 6.5, but the Gophers won eight again, including upset victories at Michigan and at Nebraska. (They capped the season with another bowl loss, this time against Missouri.)

This year's Gophers schedule will be even more difficult, with games against TCU and Ohio State again, and a difficult Week 2 test at Colorado State. Oddshark currently lists the Gophers as 16-point underdogs, at home, for their Sept. 3 season opener against TCU.

Here's a look at Bovada's over/under for the rest of the Big Ten, with 2015 Gophers opponents in bold:

Illinois: 3.5

Indiana: 6

Iowa: 7.5

Maryland: 4.5

Michigan: 7.5

Michigan State: 9.5

Nebraska: 8

Northwestern: 6.5

Ohio State: 11

Penn State: 7.5

Purdue: 4

Rutgers: 5

Wisconsin: 10

And for the Gophers' four non-conference opponents:

TCU: 10

Colorado State: 7.5

Kent State: 4.5

Ohio: 5
