Interviews. Physicals. On-court drills.

For the 63 players assembled here for the annual NBA Draft Combine, the Windy City will feel like Whirlwind City over the next few days.

For the Orlando Magic, what happens here could impact their franchise for years to come. The Magic would boost their ongoing rebuilding efforts if they correctly evaluate players and make the best use of their top-four pick in the upcoming draft. An incorrect evaluation and a bungled pick would be costly.

Magic officials already have scouted the likes of Kentucky Wildcats center Nerlens Noel, Kansas Jayhawks shooting guard Ben McLemore and Michigan Wolverines point guard Trey Burke for months and months. Until now, however, the Magic and other NBA teams haven't been permitted to sit down and speak with any draft prospect.

General manager Rob Hennigan and assistant general managers Scott Perry and Matt Lloyd are conducting the Magic's player interviews, which began Wednesday night. Each team may interview a maximum of 18 players, and the Magic are likely to speak with Noel, McLemore and Burke, in addition to 15 other players in 30-minute sessions.

Hennigan would not comment about his team's goals for the combine, but the interviews will play a critical role for the Magic, especially since many players won't participate in the on-court drills scheduled for Thursday and Friday at a Chicago gym.

The Magic won't know where, exactly, they'll pick in the first round until the NBA draft lottery takes place Tuesday in Manhattan.

Orlando, which finished the 2012-13 season with a league-worst 20-62 record, will enter the lottery with a 25.0 percent chance of winning the top overall pick, the highest probability of any team.

The Magic will have a 21.5 percent chance of securing the second overall pick, a 17.8 percent chance of receiving the third pick and a 35.7 percent chance of obtaining the fourth pick.

Most experts regard this draft class as one of the weakest in years. No one player, the so-called experts say, is a sure bet to become a perennial NBA All-Star in the mold of 2011 top overall pick Kyrie Irving and 2012 top pick Anthony Davis.

But several players currently at the top of most draft boards could develop into All-Stars.

Noel, who is 6 feet 10, might be the most impactful of the bunch when he's healthy — emphasis on the word "healthy."
