GCU and Seattle join the WCC. Don't know much about SU, but GCU is on the rise.
They are a great fit for the conference. They are a faith based school, have a great coach, and they out recuit ASU locally. Awesone facilities and a rabid fan base. They are fully invested in MBB.
With the exceptions of Gonzaga, St Mary's, and maybe San Fransisco, they can compete with anyone in the league right away. Hard to win on their floor. Just ask SDSU.
