TALLAHASSEE, FLA. ? North Carolina coach Roy Williams was worried that points were coming too easily against Florida State.

He was right.

The Seminoles erased a 24-point deficit and stunned the No. 7-ranked Tar Heels, 90-81, in overtime Thursday night, ending a four-game losing streak.

Florida State seemed completely overmatched as North Carolina’s accurate shooting helped build a 42-18 lead with just more than five minutes left in the first half.

“It was fools’ gold for us, making all the jump shots and thinking it was going to be easy,” Williams said.

Tim Pickett scored six of his 30 points in overtime for Florida State, which scored the first 11 points of the extra period.

Seminoles reserve point guard Todd Galloway tied it on a three-pointer from the corner with 7.2 seconds remaining in regulation, tying the game for the first time since the opening tip.

Rashad McCants and Melvin Scott each hit four three-pointers in the first half for North Carolina. They keyed a 21-0 run that gave the Tar Heels their big early lead.

The Seminoles (13-5, 2-3 Atlantic Coast Conference) scrambled back to trail 49-35 at halftime on a basket by Galloway, who raced the length of the court and was going up for a layup when the red light came on the backboard.

Florida State's Tim Pickett, center, is surrounded by fans following the Seminoles' victory over No. 7 North Carolina. Pickett scored 30 points, and FSU upended the Tar Heels, 90-81, in overtime Thursday in Tallahassee, Fla.

The basket was ruled good and later became an important two points.

“This is a very significant win for our team because North Carolina represents the tradition in basketball we’re trying to get to,” Florida State coach Leonard Hamilton said. “We’re the kind of team, in order to be successful, we have to be playing all out.”

The Seminoles closed to 53-43 early in the half, but North Carolina (11-4, 1-3) built an 18-point lead, 67-49, with 12:33 left.

Then Pickett went to work, driving to the basket often and getting to the foul line. He made 11 of 13 free throws and led the Seminoles with nine rebounds.

Pickett, who had just eight points at halftime, scored 13 in the final 11:22 of regulation to lead the comeback. Johnson, who started overtime with a basket, added 15 points.

Riding the momentum of a stunning rally, the Seminoles quickly took control in overtime. McCants hit a three with 20.4 seconds remaining for North Carolina’s only points in the extra session.

When the final buzzer sounded, fans poured onto the court in celebration.
