ORLANDO, Fla. -

The Orlando Magic take the first step in the post-Dwight Howard era Friday night when they open the season at home against the Denver Nuggets and it's still anyone's guess as to what direction they are headed.

Howard was traded to Los Angeles last August. Gone too in offseason trades are power forward Ryan Anderson and shooting guard Jason Richardson, which means the Magic are without three of the four top scorers from last season.

In fact, the only holdovers from last year's regular season rotation are guards Jameer Nelson and J.J. Redick and forwards Glen "Big Baby" Davis and Hedo Turkoglu. Throw in rookie head coach Jacque Vaughn, who brings a new style of play, and it's easy to understand why no one knows how the season will unfold.

"You can't put a timetable on something like this," Nelson said. "We don't know how many wins we're going to have or when we're going to be playing our best basketball, but I know that we work hard every day we're in the gym and it's going to pay off at some point."

Aaron Afflalo said low expectations for the Magic serve as motivation.

"A lot of people have us projected to finish last," said Afflalo, who was part of the four-team, 12-player trade package the Magic assembled when they sent Howard to the Lakers. "That lack of expectations is a great incentive for us to compete and do it with a chip on our shoulder. There's nothing wrong with that. We should use anything and everything to fuel our motivation in terms of how hard we compete."

Nikola Vucevic, who played in 51 games for the Philadelphia 76ers last season, will replace Howard in the Magic's starting lineup. The 7-foot Vucevic started 15 games for the Sixers and averaged 5.5 points and 4.8 rebounds, but has no illusions about making people forget Howard.

"Dwight is the best center in the league, you can't replace him," Vucevic said. "I will try to rebound, defend the lane and maybe contribute on offense, but I am still learning to be consistent."

Howard, an All-Star his last six seasons in Orlando, averaged a team-high 20.6 points and a league-high 14.5 rebounds last season, but not everyone thinks his leaving is going to be a bad thing.

"Him being gone means it's somebody else's time to arrive," Glen "Big Baby" Davis said. "Who is it going to be? I think it's going to be me."

Davis led the Magic in scoring during the exhibition season with 16.9 points a game. For his five-year career, Davis has averaged 7.9 points and 4.3 rebounds while starting 44 times for Boston and Orlando. He is a full-time starter for the first time in his career and said people may be surprised at what they see.

"Every opportunity I got to be a starter, it was like wow! He's capable of doing these things?" Davis said. "People kept saying 'When can we see the Glen Davis we saw in the playoffs, the guy who hit the game-winning shot when he replaced Kevin Garnett (in Boston) and scored all those points in last year's playoffs (for Orlando)?' Well, now it's time."

And then there is Vaughn, at 37, the youngest head coach in the NBA. He spent the last two seasons as an assistant to Gregg Popovich in San Antonio and has played for legendary coaching names like Jerry Sloan at Utah and Roy Williams at Kansas. He spent 12 years in the NBA, mostly as a backup point guard, and won an NBA title with the Spurs in 2007.

He said he expects his team to play at a much faster tempo than they did when Howard was the focal point at both ends of the court and the Magic were strictly a half-court team. Orlando was 2-6 during the exhibition season, a feeling out time for both players and coach.

"We want to play with pace and we want to share the basketball," Vaughn said. "I saw that at times during the exhibition season. We had a couple of games where we had over 30 assists.

"I think we're still in the process of learning. When the games become real and they mean something in the won-loss column, you learn something more about individuals. There is still some learning from me to be done about guys on this roster."
