AUSTIN, Texas -- The operative phrase this time of year "survive and advance" sometimes serves to take aesthetics out of the equation.
The Illinois Fighting Illini survived an 11-minute stretch without a field goal to start the second half and advanced by claiming a 57-49 victory over Colorado on Friday afternoon at the Frank Erwin Center.
Illinois moves on to play Miami in the East Regional on Sunday in Austin with a berth in the Sweet 16 at stake.
The Buffaloes erased a 16-point halftime deficit by opening the second half with a 23-2 run.
Illinois went the first 11:28 of the second half without a field goal and scored just two points on Tracy Abrams' two made free throws.
Meanwhile, Colorado bounced back from a 7:14 scoreless drought at the end of the first half. Buffaloes guard Askia Booker got particularly hot, hitting three 3-pointers during the surge.
It was Abrams who finally hit a runner down the lane to break the Illinois drought and loosened up the Illini. D.J. Richardson and Brandon Paul followed in short order with 3-pointers that put Illinois back ahead, 48-44, with 6:03 to play.
This time, Illinois (22-13) didn't give up the lead. Brandon Paul went 7-for-8 from the free-throw line in the final 5:18 to help the Illini hold on.
Abrams made the key play of the closing minutes when he missed a 3-pointer but got his own rebound with 1:10 left. Abrams passed to Paul, who was immediately fouled. Paul went to the line and hit both ends of a 1-and-1 to increase Illinois' lead to 52-46.
Paul finished with 17 points to lead Illinois.
Illinois finished the first half on a 13-0 run to take a 37-21 lead to the break.
The Fighting Illini filled up the basket from 3-point range while Colorado (21-13) was stone-cold. Richardson hit a pair of 3s and Abrams added another with three seconds left in the half. Illinois was 6-for-16 from beyond the arc in the first 20 minutes.
Meanwhile, Colorado failed to score in the final 7:18 of the first half. Andre Roberson made a layup on an assist from Spencer Dinwiddie to cut Illinois' lead to 24-21, but the Buffaloes missed their final 11 shots of the half.
Paul sparked Illinois with the Illini trailing 15-11 in the early going. Paul hit a jumper and a 3-pointer, then Tyler Griffey and Richardson added 3s as Illinois went in front 22-17 and wouldn't let go of the lead until midway through the second half.
Richardson finished the first half with 11 points, playing a key role in the Illini's 26-6 overall run.
