The 3 most savage moments of Baker Mayfield's career

Baker Mayfield is a savage.

The star quarterback proved it once again Saturday, celebrating Oklahoma's win over Ohio State by planting a gigantic Sooners flag at midfield in sacred Ohio Stadium. It wasn't the first time Mayfield has showcased his ferocity:

3. Feud with TCU

Mayfield's beef with TCU began when he was still in high school. The former Lake Travis star was all set to sign with the Horned Frogs on National Signing Day in 2013, but there was just one problem: TCU never presented him with any papers to sign.

"They told me they were gonna offer me a scholarship and kind of drug it out, and I told other schools I wasn't interested because I thought I was going to go there, and I truly believed they were going to offer me because they told me that," Mayfield said in December 2015. "They disappointed me and kind of hung me out to dry right before signing day."

Mayfield then went directly after TCU's coach, saying of Gary Patterson: "He doesn't like me, and I have no comment about that."

The jarring remarks came weeks after TCU quarterback Trevone Boykin accused Mayfield of stealing signals from the Frogs during their tilt with the Sooners.

"Old Baker Mayfield was on the sidelines and calling out every freaking signal we had, so shout out to Baker Mayfield and OU for that," Boykin said after the game, which TCU still won.

Mayfield had played under TCU's offensive coordinator, Sonny Crumbie, the year before at Texas Tech.

2. 'Sucks to be a Longhorn'

Mayfield grew up in Austin, Texas, but never received much interest from his hometown Longhorns as a high school prospect - and he's never been afraid to remind them of that. After Oklahoma defeated Texas in the 2015 installment of the Red River Rivalry, Mayfield - who was sitting out the season after transferring from the Red Raiders - wrote on Instagram, "Sucks to be a Longhorn."

The post has since been removed, but the caption lives on as one of Mayfield's most savage moments.

1. Flying the flag

Mayfield made it known before Saturday night's game that he wasn't thrilled about Ohio State singing its fight song on Oklahoma's field last year. Surely, he got his revenge in the rematch in Columbus.

After leading the Sooners to a statement victory at Ohio Stadium, Mayfield waved a massive OU flag at midfield before stomping it into the ground with authority.

"Oh no he's not," play-by-play announcer Chris Fowler said as Mayfield began setting up the spike.

"Yes he is," a stunned Fowler said seconds later.
