Things weren’t going well for Iowa State football coach Matt Campbell in the first half of the Big 12 championship game on Saturday.

No. 10 Oklahoma had a 24-7 halftime lead over the No. 6 Cyclones, quarterback Brock Purdy wasn’t having a great performance, defensive back Isheem Young was ejected less than a minute into the game for targeting and, at one point late in the first half, Campbell didn’t get a call he wanted and absolutely lost it.

On 4th-and-2 on Oklahoma’s 34-yard line with about six minutes left in the second quarter, Iowa State tried to bait the Sooners to jump offsides. When the Cyclones didn’t get the call they wanted, Campbell — whose mask was not covering his face — lost his cool and unleashed a long tirade against the game’s officials.
