"I would venture to say that this is one of the gutsiest performances our team's had in a long time, not just this team, but our program," said head coach Sherri Coale. "To shoot the way that we shot and to hang around and to put ourselves in a position to have a chance to win and then to make that happen [was incredible]."
She scored the Sooners' final nine points, all in the last 2:57, including the go-ahead and eventual game-winning bucket with 2:07 to go.
Campbell even ripped down the final rebound of the game to completely seal it up after Tech forward Jordan Barncastle missed a three with one second left that would have sent the game to overtime.
"I knew that I really wasn't helping the whole game, so it was like, 'Okay, I got to help. I got to come in and be the energy,'" Campbell said. "I'm supposed to be the energy, so I came in and it just happened to go my way. I just happened to be the person that scored tonight."
But it can't be overlooked what Hand did.
Her scoring output and defensive presence allowed the Sooners to stay in the game, setting up the comeback down the stretch.
OU trailed 66-59 and hadn't made a field goal in 10:11.
At that point is when OU showed its resolve after preventing the Red Raiders from extending their lead during that stretch because of great play on the defensive end of the court.
Forward Joanna McFarland finally hit a shot, a three, with 3:55 remaining, OU's first bucket since the 14:06 mark of the second half.
"It was uncanny," Coale said. "It's one of those things where we just tried to keep talking about how to defend and try to take all the attention away from the offense. We were watching it mount on the side. That's eight in a row. That's nine in a row. That's 10 in a row. We were rebounding, though, and I think that's one of those things that can give you a little bit of life when you miss shots and it zaps you.
"But when you can get some offensive boards, it can change the way you approach the next possession, and those kind of kept us afloat when weren't able to make a basket."
In fact, the Sooners were the beneficiaries of 22 offensive rebounds.
Because of that, they won the rebounding battle 52-40.
After McFarland's 3-pointer,Campbell took over from that point on.
Even though they ultimately overcame that poor shooting stretch, the Sooners still didn't have an answer for Tech guard Christine Hyde, who finished with a career-high 21 points on 8-for-14 shooting.
But they locked down everyone else and didn't allow a single other Red Raider to score in double figures.
Guard Aaryn Ellenberg struggled to a 3-for-16 shooting performance but was the second Sooner in double figures with her 10.
The teams traded the lead 15 times and tied eight times in a fierce first half that featured 28 points in the first four minutes and change.
OU had a narrow one-point lead at intermission, when it led 37-36.
It remained extremely close for the first 6:50 of the second half, and in fact, during that time period, neither team led by more than three.
Tech began to open it up after that point when it emerged with a 61-54 advantage at the 8:54 mark.
That was as much as the Red Raiders could string it out, though, before the Sooner comeback.
The Sooners were outshot 38.7 percent to 34.3 percent, but won points in the paint 30-22.
OU (10-4, 2-1 Big 12) escapes with a huge road victory on its way to Stillwater for a Bedlam matchup with the Oklahoma State Cowboys.
The two are set for an 11 a.m. Saturday tipoff.
