NFC Playoffs: Seahawks at Packers
This time, perhaps Matt Hasselbeck (left) will keep his yap shut. In the 2004 playoffs the Seattle QB announced after winning the OT coin toss, "We want the ball, and we're going to score!" Then he threw a pick that Al Harris returned for a TD and a Green Bay win. Hasselbeck earned a shot at revenge by throwing for 229 yards and the goahead TD in Seattle's win over Washington last Saturday.

No. 7 Georgetown at No. 13 Pittsburgh The Panthers won't have to head to their school's renowned Supercomputing Center to figure out how today's opponent is 11--1. The Hoyas are the top shooting team in the country (52.6%) and are holding their opponents to 35.2% from the floor, which is second in the nation. A big reason they're tough at both ends of the floor is 7' 2'' center Roy Hibbert, who rarely misses in the paint and is third in the Big East in blocked shots.

Australian Open
The courts in Melbourne got a makeover: They're now covered by a surface called Plexicushion. America's James Blake thinks the change from the old hard court to cushioned acrylic was made in part to help local favorite Lleyton Hewitt (above), who likes to play on a fast surface and is trying to become the first Aussie to win Down Under in 32 years. But last week's Hopman Cup in Perth was played on Plexicushion, and the results were surprising. "It seems quite slower," said Jelena Jankovic. "The balls get really fluffy."
