The Pac-12 expansion waiting game − the one it is reportedly playing almost exclusively with Memphis − continues.

Memphis football opens conference play on Saturday against Navy. Here's a scouting report and score prediction for the game.

Shortly after Oregon State and Washington State secured commitments from four Mountain West members last week to reinvent the Pac-12, OSU athletic director Scott Barnes said he envisioned the conference adding at least two more institutions "as quickly as possible.

It makes sense. The Tigers are one of the top Group of Five schools in the country, and any Group of Five (soon to be Group of Six) conference would likely target Memphis. The Pac-12 would have to go after at least one more school, and could look to the AAC — Tulane, UTSA and South Florida are all attractive candidates.

New Tulane athletic director Davis Harris, whose degree of interest in changing conferences is not clear, declined comment as per his policy on all realignment issues.
