One of these two Group of Five teams could barge into the CFP

Boise State’s ability to run the ball efficiently and create turnovers gives it a formula that could be problematic for any top team the Broncos face. Lanning called their defense "exotic."

“They do a lot of different things. I think they create, you know, preparation — it makes it tough because of the different units they use and how much they move around," he said, per On3.com. "Do a really good job mixing coverages and changing things. So, it’s a tough one to prepare for.”

If Boise State continues its early-season success and win the Mountain West championship, the Broncos could be a dark horse in the CFP race.

UNLV’s go-go offense and ground game

UNLV is another surprise in the Group of Five, thanks in large part to offensive coordinator Brennan Marion’s “Go-Go” offense, which features a two-running back formation. The Rebels’ ground attack is one of the most formidable in the country, averaging 349 rushing yards per game (third nationally), according to the NCAA. 

Last season, the Rebels ranked third in the country in rushing touchdowns with 39 and averaged 173.5 yards per game on the ground. 

This year’s attack looks even more potent with playmakers such as freshman RB Greg Burrell and sophomore RB Jai’Den Thomas. Their relentless tempo and running style wear down defenses, but they will face a major test Friday night in a nationally televised game at Kansas (1-1).

If UNLV can upset Kansas and stay undefeated, it will strengthen its case as a contender for a Group of Five bid in the CFP.

Their paths won’t be easy, but with the introduction of the 12-team playoff format, along with the right combination of wins and some chaos in the Power Five conferences, Boise State and UNLV could position themselves in the hunt for a coveted CFP spot.
