SIAP, I didn't see it anywhere. With some results this last weekend (specifically, OSU over Oregon) I can get a complete chain of suck, but I don't think a Circle of Suck is possible. Here's one of the chains; a circle requires that the last team on the end beats the first team:
CU > Cal > Arizona > UCLA > ASU > UW > OSU > U of O > Utah > USC > WSU
Congrats to CU, the 2022 Pac12 transitive champ (in the above scenario)
CU > Cal > Arizona > UCLA > ASU > UW > OSU > U of O > Utah > USC > WSU
