Big 12 College Football Playoff bubble watch, Week 9: Deion Sanders' Colorado gains relevance after Arizona matchup

The college football season is in full swing as the calendar has now passed the halfway mark with Week 8 officially in the books.

The Big 12 has been playing great football over the first eight weeks of the season, as the 16 teams have a combined record of 67-45 and 33-11 in non-conference games. There were three Big 12 teams ranked in the latest rendition of the AP Top 25 Poll.

The No. 10-ranked Iowa State Cyclones and No. 11-ranked BYU Cougars lead the way as both are 7-0 with a 4-0 mark in Big 12 play.

The Colorado Buffaloes were able to get back in the column and have already surpassed their previous season's win record under Deion Sanders.

Conference play remained in full force in Week 8 as all 16 Big 12 teams faced a conference opponent.

The expanded postseason field of 12 teams likely guarantees the conference at least one postseason seed.

Here's a look at the Big 12 teams that remain in the College Football Playoff picture.

The No. 11-ranked BYU Cougars have the third-best odds of any Big 12 program of reaching the postseason. Their +220 odds of reaching the College Football Playoff are 18th-best in the nation. They are 7-0 overall and 4-0 in Big 12 play.

The Colorado Buffaloes, with +1200 odds of reaching their first College Football Playoff in program history, are the only other Big 12 program with better than +2000 postseason odds.

They are considered a long shot to make the postseason, however, as those are just the 28th-best odds in the nation.
