For heaven's sake, Cal is going to Phoenix with a crappier record, and the payout for the Cheez-It Bowl is nearly $1 million higher than the Sun Bowl!  

Others have noted that the pay out for the particular bowl a Pac 12 team goes to doesn't really matter.
I cannot find confirmation of the $1+ million higher number.
There is a note in this thread that the Cheez-It bowl increased its payout to $3+ million. That was reported with some confidence so I suspect it's correct. What I can find in a quick web search is a lower number.
Cheez-it $1,037,118
Sun       $3,447,568

I pulled the US$ 3.35M figure for the Cheez it Bowl straight out of Wikipedia.  https://en.wikipedia.org/wiki/Cheez-It_Bowl

the footnote for the $3.35m is from 2015 so might not be current.
