We could be headed for a four-way tie atop the Big 12 entering the final week of the regular season.

No. 16 Colorado lost 37-21 at Kansas on Saturday while No. 14 BYU lost 28-23 at No. 21 Arizona State in an absolutely chaotic finish.

The Buffaloes’ defense was gashed by Kansas RB Devin Neal. The senior who grew up not far from the University of Kansas campus had 287 total yards and four touchdowns as Colorado’s defense gave up big play after big play.

BYU scored 20 points in the second half but its comeback attempt was foiled with 1:04 to go when Jake Retzlaff’s overthrown pass was intercepted by Javan Robinson. The defensive back returned the ball 64 yards before he was tackled inside the BYU 10-yard line to seal the game. Or so we thought.

Instead of trying to score the TD and get a two-score lead, Arizona State inexplicably tried to run the clock out. Sam Leavitt’s pass to try to end the game landed in the stands with one second to go. That gave BYU a Hail Mary attempt from its own 44 yard-line because Leavitt ran backward on second down to burn time.

The final play was delayed over 10 minutes because of a replay review and because the field needed to be cleared of the students who rushed it thinking the game was over.

And BYU almost pulled off the miracle win once the field was clear. Chase Roberts appeared to catch Retzlaff’s pass, but he was tackled short of the end zone (the play was officially ruled incomplete, though it likely would have been overturned if it mattered).

Colorado and BYU entered Week 13 tied atop the Big 12 at 6-1 in the conference while Arizona State and Iowa State were at 5-2. If the Cyclones win against Utah on Saturday night, all four teams will be tied at 6-2.

Kansas makes history

The Jayhawks improved to 5-6 overall (3-5 Big 12) with the win and set an FBS first. Thanks to wins over Iowa State and BYU over the previous two weeks, Kansas is the first school to ever beat three consecutive ranked teams while having a losing record.

Neal had 37 carries for 207 yards as Kansas rushed the ball 57 times for 331 yards. Colorado can be vulnerable to opponents’ run games and the Buffs can’t run the ball themselves. Colorado rushed 13 times for 42 yards.

Kansas’ run game allowed it to control the ball against the Buffaloes. Kansas had the ball for over 40 minutes as Colorado ran just 42 plays to Kansas’ 58.

Travis Hunter didn’t do anything to ruin his great chances at the Heisman in the loss. Hunter had eight catches for 125 yards and two touchdowns while also playing on defense.

Who has the advantage to make the Big 12 title game?

Arizona State has the best chance of anyone to make the Big 12 title game. The Sun Devils are in with a win over Arizona in Week 14.

Colorado, meanwhile, needs help if there’s a four-way tie at 7-2 and Iowa State beats both Utah and Kansas State in its final two games.

If all four teams end up tied atop the conference, the first tiebreaker would be against their common opponents of UCF, Kansas, Kansas State and Utah. Colorado is cooked in that tiebreaker with losses to the Jayhawks and Wildcats. ASU is 4-0 against those teams and Iowa State and BYU would be 3-1.

After that tiebreaker, it would progress to the winning percentage of conference opponents. In that tiebreaker, Iowa State currently has the edge.
