Bequette sacked the South Carolina quarterback three times, including a brutal hit with 5:12 left to clinch a 44-28 victory to validate the Razorbacks' spot in the top 10 and perhaps define the season for both teams yet again.
There was a real earthquake that rocked the stadium about one hour after the game. The upper decks on both sides shook for nearly 30 seconds. Earlier, Shaw lay prone on the turf from Bequette's hit for much, much longer.
There were no more quarterback draws left in him at that point. Bequette knocked him silly and the ball loose on a first-and-20 play with Dede Jones covering it at the Carolina 1-yard line. Broderick Green put the Gamecocks out of their misery two plays later.
Arkansas kept out hitting the No. 9 Gamecocks and took advantage of superior speed in so many skill position matchups. Bequette thought it was enough to silence the critics – national and around home – who have questioned their mettle and poll position.
"I'm proud of our guys," Bequette said. "There have been a ton of distractions. Our fans have called us out. There have been a lot of people saying that we were not really a top 10 team. Maybe we proved we belonged tonight."
Bequette proved part historian as well as Shaw's undoing off the edge.
"This game has decided both teams fortunes a lot through the series, for a long time," Bequette said. "We knew that. We knew how big it was for our season.
"So we circle this game every year. We knew we got a resounding win against them last year, too. So that gave us confidence for this game."
The Hogs did whack the Gamecocks, 41-20, last year in Columbia. Some of the Gamecocks mentioned that they really weren't focused on the Hogs with the key SEC East matchup looming the next week against Florida. There will probably be no such talk this time.
"Yeah, I think we got their best shot," Bequette said. "They played really hard. They knew what this one meant. They played really hard."
They just were not nearly as good as the Razorbacks. The trench wars went the way of the home team on both sides of the ball. Bequette said head coach Bobby Petrino "challenged" the defensive front to outslug the Gamecocks all week in practice.
"We emphasized that we needed to be the more physical team, like we were the last two years against them," Petrino said. "And our offensive line got tired of hearing about their defensive front about halfway through the week."
Bequette said, "Coach Petrino said it was time to crank up the sacks. The defensive line knew we had to put pressure on Shaw. It was on us after Coach Petrino challenged us.
"We were going to go after him and put pressure on him. We knew he wasn't as good when you get pressure."
Defensive coordinator Willy Robinson said it was a matter of the Hogs finally playing to their potential.
"That's what we can be when we all play together," he said. "We haven't done that. We played tonight. You saw the difference.
"Obviously, it helps to have Jake back close to being healthy (from an early-season hamstring pull). He's faster than he was a few weeks ago. And he was relentless tonight. We got some one-on-one matchups on the edge for him and he took advantage of them.
"We are starting to get healthy and it shows. We are still missing one more key element (in end Tenarius Wright), but we are getting closer."
While Shaw was taking a beating, Arkansas quarterback Tyler Wilson did his best Houdini act to avoid one of the nation's fastest groups of ends. The Hogs did just enough in the running game to get their play-action game going and Wilson proved elusive in the pocket – when it was set or when they moved it.
"We had some new wrinkles to get away from their rush," Wilson said. "I tried to step up between the tackles some and we rolled out some. We did some things to slide around.
"We knew they were good outside, but we saw some things we could do that would give me some angles to throw some of those passes that I can throw. So we moved the pocket around and got those different slots."
Wilson gave up the pick six when he tried one of his sling throws while going to the ground on a rollout. But he followed that with a 68-yard touchdown strike to Jarius Wright on the next play.
"Tyler did a good job," said Garrick McGee, offensive coordinator. "He did make some mistakes, but he made enough plays for us to win.
"Here's the thing about Tyler, he just needs repetitions. He's in his first year. He's getting more and more reps, getting more and more comfortable. He misses some things, but he makes enough plays, too."
Robinson said it was a fun night in a great setting.
"We were very excited," he said. "Our players all played fast. They practiced fast this week, too. They had a great week of practice. You could tell they wanted this game.
"The thing about it, this is the kind of feedback – winning a game like this in front of this crowd – that should give them confidence that they can play like this. It should be huge for us."
Bequette said it can get better, too.
"I'm not going to lie and tell you I'm 100 percent," he said. "I'm not all the way back. I'm better and definitely faster. But I should get faster."
Robinson shuddered at that thought.
"I saw the way he hit that quarterback," Robinson said. "I heard it and I had headsets over my ears."
It was like the earth moved around Razorback Nation and maybe it did.
