Orlando Magic 2012 training camp opens with some big questions

Clearly, the biggest questions involve Orlando's rotation and how its mostly young team will fit into new head coach Jacque Vaughn's system.

However, Orlando's roster is full of question. After signing free agent guards Armon Johnson and DeQuan Jones last week, the Magic enter camp with 19 players on their roster, meaning they must release at least four players before the season starts. Jones and Johnson are obvious candidates to be released. Other players who will have roster spots in questions are wing Christian Eyenga, forward Justin Harper and forward Josh McRoberts, among others.

Johnson is also involved in another one of Orlando's biggest competitions -- backup point guard. Incumbent starter Jameer Nelson signed a three-year deal in the offseason and the Magic decided to bring back Ish Smith, their third string point guard at the end of the season.

The Magic believe E'Twaun Moore, a 6'4 guard who averaged 2.9 points, 0.9 rebounds and 0.9 assists for the Boston Celtics last year, can be a ball handler as well.

Johnson, at 6'4, also has great size, but like Moore and Smith, he has little experience. Johnson has appeared in just 47 career games, averaged 5.6 points, 1.5 rebounds and 1.4 assists in nine games with the Nets last season. Moore has appeared in 38 career regular season games and nine career playoff games. Smith has appeared in 69 career games, including 20 with the Magic last season (averaging 2.3 points, 1.6 assists and 1.4 rebounds per game).

Glen Davis, Orlando's leading scorer in the 2012 postseason, looks like he will remain at power forward despite the success he had at center in Dwight Howard's absence last season. First round pick Andrew Nicholson and veteran Al Harrington will also see some time in that spot. The Magic have Nikola Vucevic and Gustavo Ayon, two promising young players, at center. Plus, second-round pick Kyle O'Quinn played center during summer league.

Shooting guard and small forward seem a little more clear. Veteran Arron Afflalo joins J.J. Redick at the two while rookie Moe Harkless joins Hedo Turkoglu at the three. Eyenga, Harper and Jones will battle them for playing time.

The Magic open the preseason against the New Orleans Hornets in Mexico at 2:30 p.m. ET Sunday. The game will be shown on NBA TV.
