The University of Colorado team can only keep the bubble from bursting at this point.

Beyond that, the Buffaloes' postseason fate may be out of their own hands.

The final regular-season series of the year is on deck for the Buffs, who host Washington State on Wednesday afternoon at 2 p.m. before closing the 2015 campaign against Utah on Friday at noon.

The up-and-down season turned in by CU has left the program at the cusp of consideration for the NCAA tournament. Entering the final set of games the Buffs rank No. 66 in the critical RPI rankings, leaving CU on the outside looking in for the 64-team NCAA tournament field.

Wins against Washington State, ranked at No. 112 in the RPI, and Utah (No. 126) won't necessarily send the Buffs into a less precarious postseason position. However, CU could still move forward if the teams immediately ahead of them in the RPI stumble this weekend, and a loss in either match this weekend would almost surely end the Buffs' NCAA dreams.

That said, garnering a pair of wins will allow the Buffs to provide an interesting dilemma for the NCAA selection committee to mull before announcing the tourney field Sunday night. Such a scenario would leave CU alone in fifth place in the Pac-12 Conference, widely considered one of the best volleyball leagues in the nation. The Buffs would be ahead of Arizona State, ranked 33rd in the RPI and a team CU split matches with this year, as well as Arizona, which is No. 41 in the RPI but has lost twice against the Buffs.


CU also has posted wins this season against Florida State (No. 22 RPI) and Stanford (No. 12).

The Buffs suffered a four-set loss that was hurtful to their RPI at Utah on Sept. 23, one of just four league wins for the Utes this season. In the unbalanced schedule of the 12-team league, Wednesday will mark CU's only contest against Washington State.
