Assuming Iowa State and Colorado win out and KSU loses to Iowa State, it's pretty simple:

• Any single loss is fine as long as we win the rest
• Any 2 losses will knock us out

On the other hand, if Iowa State loses to KSU and both KSU and Colorado win out, we can afford these loses and still make it to the CCG:

• An ASU loss still keeps us in
• A Houston loss still keeps us in

A loss to Utah or Kansas will knock us out. Any 2 losses will knock us out.

In other words, the Utah and Kansas game are the most important games left on our schedule.  2 losses and there is a chance we are left out entirely.
