Texas A&M, though, had already announced its decision to leave the Big 12 for the Southeastern Conference when Williams chose to transfer.
Notre Dame coach Brian Kelly has also come under some heat this week after his decision to not release five-star defensive line signee Eddie Vanderdoes from his National Letter of Intent.
Vanderdoes signed with the Fighting Irish in February, but decided to enroll at UCLA instead and stay closer to home.
Because he backed out of his LOI and Kelly didn't grant him a release, Vanderdoes loses a year of eligibility that can't count as a redshirt or a transfer year.
“I'm on the side of the coaches,” Stoops said. “I'm on the side of Mike. I'm on the side of Brian Kelly at Notre Dame. I see why. They've left us in a bad position because now we're short-handed.
“He committed to us. He signed with us. ... When you sign, you know what you're committing to.”
