SAN JOSE, Calif. -- Xavier coach Chris Mack walked to the halftime locker room with an assertive stride: "Count it," he said as the officials went to the monitors to see if J.P. Macura, who had just banked in an 80-footer at the buzzer, had gotten his shot off in time.

Macura had not, but you couldn't blame Mack for trying. With 20 minutes of season-defining basketball still to come, his team was already drowning in Gonzaga's relentless offensive flood.

The flood never stopped.

Gonzaga is headed to its first Final Four after an 83-59 victory Saturday in the West Regional, and whereas the Zags reached the precipice of that accomplishment with Thursday's grounded, defensive holdout against West Virginia, the final breakthrough came in a fiery supernova of buckets.

Against a tricky, shifting Musketeers defense that dominated Florida State and held Arizona scoreless for the final three minutes of Xavier's Sweet 16 win, Gonzaga scored 83 points in 71 possessions. The team shot 12-of-24 from 3. The Musketeers executed their own plan on the offensive end in the first half, hammering the ball at the rim at every opportunity, and got 39 points in 35 possessions against the nation's stingiest per-possession defense. But they made just one 3 in the first 20 minutes -- Macura's miracle heave would have been the second -- and went to the locker room down 10. Gonzaga had already made eight 3s.

All-American guard Nigel Williams-Goss, who had made just one 3-pointer in his first three tournament games, went 4-of-7 from beyond the arc Saturday. Josh Perkins went 3-of-7. Johnathan Williams was unstoppable whenever he touched the ball.

It was an offensive blowout, a remarkable display of the other side of Gonzaga's 36-1 record and proof that there is nothing, on either end of the floor, this team cannot do.
