Among assistant coaches, Will Muschamp was the single-most splash hire in college football last offseason.

Auburn handed the former Florida head coach a contract worth $5.1 million for three years. Pairing Muschamp, a renowned defensive coordinator, with Auburn coach Gus Malzahn, an “offensive genius,” was supposed to pay big.

The media even picked Auburn to win the SEC this year after the hire.

Instead, the Tigers finished 6-6 in the regular season. Now it appears the Malzahn-Muschamp marriage already is over.

“It seems only a matter of where, not when,” AL.com reported Thursday.

According to one report, he most likely is destined to be the next coach at South Carolina.

Other options for Muschamp include the defensive coordinator job at either Alabama (under Nick Saban) or Georgia (under Kirby Smart).

Muschamp’s contract with Auburn is such that he can leave after the SEC championship game has ended and not owe Auburn a cent.

“Philosophically, Muschamp leaving for a head coaching position would make sense. That’s his goal,” AL.com wrote. “But leaving for another coordinator position would have to be considered a sign that he has serious questions about the future of the program.”

Wherever Muschamp goes, he could take secondary coach Travaris Robinson with him. That would be a huge blow to Auburn’s 2016 recruiting class, not to mention the defense.

Though the Tigers rank low in most statistical categories this year on both sides of the football, the defense improved as the year went along. Auburn could also be losing its best defensive player, edge rusher Carl Lawson, and will lose its two standout senior linebackers.

Malzahn, hot seat. Hot seat, Malzahn. Pressure is coming in bunches for 2016.
