Depending on your draft order, I would go with LBJ as your first pick. He brings a whole lot at a young age (only 22)(31 ppg, 6 rpg, 6 apg, 1 spg, near 1 bpg, 48% FG, 75% FT, couple of 3's). Basically, he can light up a scoreboard every night, so he's a consensous #1 pick. You can select from these other if you can't get LBJ:
-Kevin Garnett: Despite the lack of threes, he can contribute all-around for a big man and a better supporting cast (Mike James, Randy Foye, Ricky Davis) should put a stellar year for him (20 ppg, 12 rpg, 6 apg)
-Shawn Marion: The Matrix should benefit with 2-time MVP Steve Nash running the show and the return of Amare Stoudamire should get some pressure off Marion, which mean another all-around season (18 ppg, 9 rpg, 1.0 spg, 1.0 bpg, 48% FG, 80% FT, 1.2 TO).
-Dirk Nowitzki: Forget that he collapse in the NBA Finals and think about the 20 ppg and 9 rpg he's going to post this season, along with a couple of threes and good shooting percentage. Basically, he's a taller and better version of Ray Allen with the same suporting cast from the NBA Finals.
-Gilbert Arenas: Forget the groing issue, the former 2nd round pick is already excelling as the best PG (sorry Nash), as he can score big time and pass also with everything a PG need to do (withing exception with the 3.0 TO).
