Utah's rookie point guard Deron Williams had 18 points and three assists, and played the entire fourth quarter while the Jazz rallied to beat the travel-weary Dallas Mavericks 93-82 Wednesday night.

``I just feel comfortable being in those type of situations,'' said Williams, the third overall selection in the 2005 draft. ``I've been in them a lot in college and I don't see why it should be different now.''

The last game Williams played in that counted was the NCAA championship, when North Carolina beat Williams' Illinois team for the national title. He made his first NBA shot -- a 3-pointer -- in the second quarter Wednesday and beat the third-period buzzer with a 61-foot shot that sparked Utah's comeback.

Williams also had just one turnover.

``He played OK. It was his first game and he knew what he was doing,'' Jazz coach Jerry Sloan said. ``He played in control and sometimes he got a little confused, but we expect that. I thought he played pretty well.''
