FORT WORTH, Texas -- TCU coach Gary Patterson was unhappy with the officiating during his team's 52-46 home loss to Oklahoma on Saturday, including an intentional grounding call made on the Horned Frogs' final offensive drive.

Patterson said he did not believe TCU quarterback Kenny Hill should have been flagged for grounding on a drive that ultimately failed in four plays and yielded minus-10 yards, securing the Sooners' victory.

"The bottom line to it is, in his estimation, [Hill] didn't have anyone to throw to," Patterson said of the official who threw he flag. "Mine was he got hit, so I don't know how he can tell he couldn't throw it to him."

The officiating crew initially determined there was no penalty, but Oklahoma coach Bob Stoops successfully argued with them that Hill was still in the pocket and that no receiver was near the ball.

"They were already going back to tell him there was nobody there in that area, [which] is what we were yelling about," Stoops said. "And then initially he said [Hill] was out of the pocket, and I was like, 'He didn't take one step to get out of the pocket. He was right back where he started.' But fortunately, they talked that through, too, and I believe they really got it right."

Patterson was also frustrated that Oklahoma was not penalized for holding "when it mattered," and said Oklahoma RB Joe Mixon should've been called for holding in the second quarter on a touchdown play when he "just tackled my guy." The Sooners were flagged twice for holding during the game.

While making his comments about the game's officiating, Patterson took an apparent shot at Oklahoma quarterback Baker Mayfield.

"You know, it's amazing, we can't say anything, but they can do whatever they want to," Patterson said of the officials. "So I don't really care right now if the commissioner, if they don't like what I think about what happened with the officials.

"We talk about sportsmanship in this game, and I've got a quarterback that writes a whole article on me, how I treated him wrong. But I can't talk about officials. Bottom line to it is, I wasn't happy with the officiating."

Mayfield was recruited by TCU out of high school but ultimately did not receive a scholarship offer. He told reporters in December that TCU "kinda hung me out to dry right before signing day," which Patterson denied and responded to by saying, "If people knew the whole story, they might not have a great opinion of Baker or his father."

"We talk about sportsmanship in this game, and I've got a quarterback that writes a whole article on me, how I treated him wrong. But I can't talk about officials. Bottom line to it is, I wasn't happy with the officiating."

In an ESPN The Magazine story published in August, which Patterson appears to be referring to in his postgame comments, Mayfield's parents again criticized how TCU handled the recruitment and acknowledged the Mayfield-Patterson feud worsened in 2014 when Mayfield was caught stealing TCU's hand signals for playcalls on the sideline during the Frogs' win over the Sooners.

Despite his frustration about officiating, Patterson did praise Oklahoma for coming into his stadium and pulling off the victory. The Sooners trailed 21-7 after one quarter but rallied with a 42-3 scoring run over the second and third quarters. TCU mounted a 22-point comeback in the fourth and got the ball back down six with 1:49 left. The Frogs' drive stalled after two penalties and Hill's fourth-down pass fell incomplete.

"We're not happy about a 6-point loss, simple as that," Patterson said. "That's not what this program's about. I didn't know if we had the people to be able to challenge for a conference championship, but the bottom line is to it, we're dang sure gonna try to."
