On Saturday afternoon, bookmakers at the Westgate SuperBook gathered around the computer to see where they stood after what they thought had been a successful start to the college football slate for the house. They couldn't believe what they saw.

"We were like 'how in the hell are we losing?'" SuperBook assistant manager Ed Salmons said with a chuckle.

The culprit was a $320 three-team European soccer parlay featuring three draws that hit for $50,000.

It was only a small setback, though, on what turned out to be a highly-profitable day for the books.

College football underdogs went 28-20 ATS and pulled off 13 outright upsets on what multiple books said was the most lucrative Saturday of the season for the house to this point.

Saturday would have gone from great to historic at the SuperBook, if Wisconsin had knocked off Ohio State and if NC State had pulled the upset against Clemson.

The Buckeyes rallied from a 10-point deficit to beat the Badgers in overtime. NC State missed a 33-yard field goal on the final play of regulation and ended up losing to Clemson 24-17 in overtime.

"We probably had as good of a Saturday as we've had all year," Salmons said. "Those two games could have just put it to one of the best Saturdays ever."

Hawaii covering the spread against UNLV and UCLA covering against Washington State were positive swings for William Hill at the end of the day. "It could have been great if Wisconsin would have held on [against Ohio State]," spokesperson Michael Grodskysaid.

College football odds & ends

-- Colorado has covered the spread in eight straight games, the longest active streak in the nation.

-- New Mexico's last eight games have gone over the total, including Saturday's 45-40 upset of Air Force. A bettor at MGM put a "low five-figure" money-line bet on the Lobos at +375.

-- The current line on the Michigan-Ohio State game on Nov. 26 is Buckeyes -7 at the Westgate SuperBook. All the action to this point has been on the Wolverines, according to Salmons.
