Bo Wallace became a star under Hugh Freeze at Ole Miss from 2012-14, throwing for 9,534 yards and 62 touchdowns as the Rebels became a contender in the SEC West.
The former quarterback has also spent some time over the last three years criticizing his former coach in rants on Twitter that spanned several posts.
After Freeze was fired as Auburn's head coach on Sunday, the Tigers went out and had their best offensive display of the season, putting up 563 total yards in the 45-38 overtime loss to No. 16 Vanderbilt in Nashville.
Wallace took the opportunity to wish another former coach of his, Derrick Nix, congratulations on Auburn's explosive offense on Saturday.
