I've seen and heard hints from two different places that he's close to being gone: the Crimson Captain's Discord server (salt to taste) and on Curry Hicks Sage's Twitter Space (he's pretty plugged into coaching searches).
My concern is with the new AD. If what I've seen suspected is true and he's really a front man for Randall Stephenson, will basketball be a priority? Does Randall care about basketball? Roger Denny is a law and operations guy...was involved with the Illinois football search, but he's never fired or hired a coach. And Joe C. is still on the payroll as an advisor. Even if we fire Porter, do we get more of the same with the next guy?
All the signs (won-loss record, decreased ticket sales) say he should go. OU has to show commitment to the program with the next coach. The fans are ready to support a winner. The fan base is checked out on Porter.
