There's no debating UCF's biggest win in school history is last January's Fiesta Bowl against Baylor which capped off a top 10 finish for the 12-1 Knights.

In the 35-year history of the program, there have been several "biggest wins." Prior to the Fiesta Bowl, it was the 2010 Liberty Bowl victory against Georgia. A decade earlier, some counted the 2000 win at Alabama as the biggest, especially after the string of heartbreaks against other SEC opponents.

But what was the first game declared to be the biggest win in school history?

UCF's 39-37 "upset" of Bethune-Cookman on Sept. 8, 1985.

After 15 consecutive meetings from 1981 to 1995, the two schools meet again in Orlando this Saturday for UCF's home opener. In 1996, UCF elevated to Division I-A (now called FBS), leaving BCU behind in I-AA (FCS) and effectively ending the Central Florida rivalry. It wasn't much of one at that point though as the Knights had won 10 of the last 11 meetings.

But in the early days of UCF Football in the 1980s, it was Division I-AA Bethune-Cookman who reigned supreme over the Division II Knights. The Wildcats won the first four games of the series and were expected to win the 1985 season opener, which marked Gene McDowell's UCF coaching debut.

In reviewing the Orlando Sentinel recap , the 1985 UCF-BCU game played out like one of UCF's dramatic finishes of 2013.

The underdog-Knights took a 19-9 advantage into the locker room at halftime. Bethune-Cookman roared back in the second half, taking a 37-36 lead on a touchdown pass with 49 seconds left. That gave UCF just enough time to put together a drive to get within field-goal range of standout sophomore kicker Eddie O'Brien, who booted a 55-yarder off the left upright but through to give UCF their landmark win. At the time it was the longest field goal in UCF and Orlando Stadium (Citrus Bowl) history.

''When I hit it, I knew I had it,'' O'Brien said afterward. ''When I kick it, I can tell. I started running to the sideline before it went through.''

It was a memorable first game for McDowell, who as athletic director and head coach helped guide the program into I-AA and later into college football's top level.

''I think they may be a better football team, but the better team doesn't always win," McDowell said in the Sentinel recap.

O'Brien, who kicked four field goals in the win, still holds UCF's record for career field goals with 50. What a postgame quote:

''I can't describe the feeling,'' O'Brien said. ''Why do drugs when I can get a high like this.''

In another Sentinel story posted after the 1985 game, Gary Silvers wrote that McDowell and O'Brien "bet cherry colas" at practice whether O'Brien could hit 65-yard field goals.

''I knew he could make it,'' said McDowell, who watched O'Brien convert a 70-yard field goal in practice last week.

UCF is expecting 40,000-plus for Saturday's game, which could reach sellout status with a strong showing from students. The 1985 BCU game set a then-attendance record, and according to the write-up, must have had quite the atmosphere:

"The attendance was as big a shock as the final score. A boisterous crowd of 21,222 turned out for the season opener, shattering UCF's record of 14,212 against Fort Lewis in 1983."
