The de facto Big East championship game between Louisville and Rutgers has been established with the Scarlet Knights’ 10-3 win over Cincinnati on Saturday.

But that’s not going to be the big topic around the Big East in the two weeks before the game in Piscataway. The Big East may yet again be the subject of conference realignment talk as reports surfaced Saturday that Maryland is in negotiations to leave the ACC for the Big Ten, a possibility that could cause Rutgers to leave the Big East to be the Big Ten’s 14th member.

As recently as Oct. 20, the Big East had three undefeated teams. Four Saturdays later, all three are sitting with at least one loss.

Despite Louisville’s loss to Syracuse in the Carrier Dome, the Big East race likely comes down to the same teams as it appeared back in early October -- the Cardinals, Rutgers and Cincinnati. The Scarlet Knights, whose lone loss is to Kent State, remains the only undefeated team in Big East play. Their tests are upcoming, starting with Cincinnati this week and Louisville in the finale.

Louisville keeps rolling along as the Big East’s only undefeated team, but the rest of the conference has serious questions to answer in the final four Saturdays of the season.

Cincinnati and USF have new quarterback concerns due to ineffectiveness or injury. Pittsburgh and Syracuse must regroup after deflating losses. Rutgers is still looking for what went wrong in two-score loss at home to Kent State. And Temple and Connecticut are searching for anything to keep them competitive in the final weeks.

If Louisville is playing with a chip on its shoulder, Cardinals coach Charlie Strong has to be pleased with the results.

Louisville is the lowest ranked undefeated team at No. 11 in the Associated Press top 25, two spots behind a two-loss LSU. The other five undefeated teams -- Alabama, Oregon, Kansas State, Notre Dame and Ohio State -- are all in the top five.

College football’s weekend slate is highlighted by key games in the SEC (Alabama at LSU) and Pac-12 (Oregon at USC). Here’s a look a every game.

Momentum for previously undefeated Cincinnati and Rutgers has been sapped the last two weeks, but the Big East has other teams starting to get hot in recent weeks.

Syracuse has won back-to-back games for the first time this season, but a game at Cincinnati will give the Orange a chance to win three consecutive Big East games for the first time since 2001. And Pittsburgh has scored a rare win streak against FBS opponents. Extending it to three will be a tough task against undefeated Notre Dame.

Just two weeks ago, the Big East was basking in the glow of three teams undefeated in October.

That number is down to one. Barely.

The three-game round robin between Cincinnati, Louisville and Rutgers may still determine the Big East championship, but some of the luster is gone after the MAC bit the Big East again this season as Toledo upset previously undefeated Cincinnati last week.

The Big East race may still be between three teams, but the race lost its luster less than a week before one of the marquee games of the season for the league.

Thank Cincinnati for that.

Here’s the good news for the Big East for the second half of the season: The league has three nationally ranked, undefeated teams in Louisville, Rutgers and Cincinnati who will all face each other in the final month. For a conference struggling for national relevance, this round robin will be a breath of fresh air.
