The billion dollar dream is over.

A second day of upsets ended any chance of someone having a perfect NCAA tournament bracket in Warren Buffet’s $1 billion challenge. It was a favorite that provided the first blemish on the final three people’s brackets in the Quicken Loans contest on the Yahoo Sports website.

All three had ninth-seeded George Washington beating Memphis. The Tigers won 71-66.

“If Warren Buffett wants to donate the (billion) to our university, we will take it and use it in good company,” Memphis coach Josh Pastner said. “We’ll find a way.”

It only took 25 games for everyone to be eliminated. Then again most of brackets were knocked out on the tournament’s first full day. The number of unblemished brackets kept dwindling after third-seed Duke, sixth-seed UMass and seventh-seed New Mexico lost Friday.

Only 16 people remained perfect after 10th-seeded Stanford topped New Mexico. Then Tennessee routed UMass, leaving only six people with a chance of beating the 9.2 quintillion-to-1 odds.

Gonzaga’s victory over Oklahoma State cut that down to the final three.

Even though no one won the $1 billion, the top 20 scores will still each get $100,000.

Quicken Loans, which is sponsoring and insuring the Buffet contest, said on its Twitter feed that it wouldn’t reveal the number of entrants to the challenge. The pool was supposed to be capped at 15 million entries. It probably wouldn’t have mattered if they had let more people join.

At CBSSports.com, only 0.03 percent of entrants were still perfect after Mercer upset Duke. They didn’t last much longer as Tennessee’s rout of UMass wiped out all the remaining unblemished entries. It took 21 games to end everyone’s hope of perfection this year. Last season it took 23 games and 24 in 2012.

A year ago, not a single person of the 11 million who entered on ESPN’s website was perfect after a first day filled with upsets. Just four got 15 out of 16 right.

This year people lasted a little longer. After 28 games, all 11 million entries had at least one mist

5 OT games most in NCAA tournament round of 64: (AP) — With four games still to be completed, the NCAA tournament’s round of 64 has never had this many games go to overtime.

When Stephen F. Austin made an improbable rally to force OT against VCU in San Diego, it was the fifth overtime game of what is now called the second round.

SFA went on to beat VCU 77-75.

On Thursday night, four round-of-64 games went into overtime to set a record for one NCAA tournament day.

The last of those 16 games — San Diego State’s victory against New Mexico State — broke the previous mark.

Before that, North Dakota State upset Oklahoma, Saint Louis beat North Carolina State and Connecticut beat Saint Joseph’s.

The final game of the First Four also went to overtime Wednesday, when Tennessee beat Iowa

Stanford knocks off No. 7 New Mexico: ST. LOUIS (AP) — Chasson Randle scored 23 points and No. 10 seed Stanford made an impression in its first NCAA appearance since 2008, leading almost start to finish in a 58-53 victory over seventh-seeded New Mexico on Friday.

The Cardinal (22-12) built an early 16-point lead then held on after New Mexico rallied to tie it midway through the second half. They got four crucial free throws from reserve Robbie Lemons and Randle in the final half-minute after New Mexico had cut the deficit to two points. They will play the Eastern Kentucky-Kansas winner on Sunday in the third round.

Cameron Bairstow had 24 points and eight rebounds but the Lobos (27-7) got off-days from their other top threats. Kendall Williams and Alex Kirk, who together average 30 points, combined for just six.

New Mexico has been one and done the last two seasons, losing as the No. 3 seed to Harvard last year under coach Steve Alford and now as the No. 7 under Craig Neal.

Stanford got away with an off-day from Dwight Powell, who missed all eight shots, fouled out and scored three points. Powell averages 14.2 points, second on the team.

Anthony Brown added 10 points and seven rebounds for the Cardinal and Stefan Nastic had 10 points and five rebounds.

Stanford hit eight of its first 10 shots and scored 17 straight points, including six from Randle, for a 20-4 lead with 13:23 to go in the first half.

New Mexico went 6:26 between points and more than 7 minutes between baskets before gaining its footing. The Lobos kept feeding it to Bairstow and ended the half on an 8-0 run that cut the deficit to 32-27.

They tied it at 45 near the mid-point of the second half before going scoreless for nearly 7 minutes.
