Texas shot respectably from field goal range, finishing the game 30-for-74 (40.5 percent). Surprisingly, UT's shooting woes came from behind the arc, as the Longhorns shot a below-average 6-for-30 from three-point range, including five missed treys in overtime.
Meanwhile, the Cyclones (11-8, 3-5) shot 31-for-67 (46.3 percent) from the field and had six players score in the double-digits. Carr led his Cyclone squad in scoring with 22 points.
Texas, which came into the contest ranked #18 in the ESPN/USA Today Coaches poll and #20 in the Associated Press poll, held a 6-point lead with just over three minutes to play in regulation, before a Cyclone surge brought the game to a tie. Gibson had a chance to give the Horns a last-minute win, but the guard fumbled the ball away, sending the game into extra minutes.
Iowa State took the lead from the games opening tip until Gibson drained a three-pointer and F Brad Buckman tacked on two points to knot the score at 5. The Cyclones then lit up the scoreboard, and a Texas shooting drought paved way for Iowa State to complete an 8-0 run. With 11:33 to go in the first half, the Cyclones extended their lead to 13 points, the largest margin in the game.
Texas pecked away at the deficit in a crowd-pleasing manner, as Gibson brought the Erwin Center crowd to its feet with a pump-fake lay-up. Gibson finished the game with 23 points after staying on the floor for the games entirety.
After exchanging a few buckets, G Kenny Taylor delivered a behind-the-head pass to F Dion Dowell, who slammed the ball down seconds after coming into the game to help Texas climb back into contention. Dowell played a career-high 24 minutes, scoring nine points. A breakaway dunk by C Jason Klotz brought the Longhorns to within 5 points with almost eight minutes left to play in the half.
As the half dwindled, Texas toyed with the possibility of catching up by the break, but the Longhorns headed into the lockerroom down 36-31.
Both teams came out firing early in the second half, but Texas struck more with a Gibson three-pointer bringing the Horns to within one point only minutes into the period. Buckman then tacked on two points to give Texas its first lead of the game with 17:28 left to play.
Buckman finished the game with 20 points and 15 rebounds. With his two blocked shots in the contest, Buckman became only the eighth player in Texas history to reach the century mark in career blocks.
Iowa State answered right back and reclaimed the lead with a pair of field goals, before Gibson connected on a lay-in and foul shot to put Texas ahead 47-45. Soon after, Dowell and Klotz had a pair of lay-ups to extend Texas lead to six points.
Forward Mike Williams then electrified the crowd with a dunk, but Iowa State crawled back into the game, trailing by only two points with 6:23 to play in regulation. Like Dowell, freshman Williams saw more action than usual, playing 21 minutes in the game.
The Longhorns grabbed their biggest lead of the game after Klotz and Gibson tacked on free throws and Buckman nailed a three-pointer with under five to play. Iowa State began draining shots, though, and G Will Blalock managed to tie the game up with 37 seconds left.
In OT, Texas chunked up three-pointers but none connected, while Iowa State shot seemingly flawlessly and finished the extra period 7-for-10 from the field.
"Its like a dagger in your heart when they just keep knocking down shots," said Buckman.
Texas, on the other hand, shot a mere 4-of-11 from the field in overtime, and Iowa State escaped Austin with a win.
Texas blamed the loss on the poor late-game outing.
"We played the way we wanted to for the first 36 minutes," said Gibson, "but in the last minutes, we made some mental mistakes."
Head coach Rick Barnes reiterated the need to end strong.
"We got to find a way to finish the game," said Barnes.
