Latest NBA mock draft: Do Pacers go big or small?

With the combine and lottery in the books, the speculation season for the 2015 NBA draft has officially begun. USA TODAY Sports' Derek Bodner revises his two-round mock based on the latest buzz.

1. T'Wolves: Jahlil Okafor, C Duke

HT: 6'11" | WT: 270 lbs | AGE: 19

General manager Flip Saunders and the Wolves are very big on Jahlil Okafor. That being said, they are still very much undecided with their top pick. It could be Okafor and or Karl-Anthony Towns.

2. Lakers: Karl-Anthony Towns, C Kentucky

HT: 6'11" | WT: 250 lbs | AGE: 19

If the Timberwolves select Okafor first, the Lakers should have an easy decision. Towns fits in well with last year's first round pick Julius Randle and will help anchor their defense for years to come.

3. 76ers: D'Angelo Russell, G Ohio State

HT: 6'5" | WT: 180 lbs | AGE: 19

Some league executives think Russell could be the best prospect in the draft, and he also fits a position and skill-set the Sixers desperately need.

4. Knicks: Emmanuel Mudiay, PG

HT: 6'5" | WT: 200 lbs | AGE: 19

The Knicks would probably prefer any of the aforementioned picks fall to them at 4, as Mudiay's questionable shooting may not fit what they are looking for in a point guard to run the triangle. Still, Mudiay is the best talent still available.

5. Magic: Kristaps Porzingis, C Latvia

HT: 7'1" | WT: 220 lbs | AGE: 19

Porzingis would fit the Magic's need for a shot blocker to put next to center Nikola Vucevic and would also help their floor spacing. Justise Winslow, Willie Cauley-Stein, and Mario Hezonja all possibilities as well.

6. Kings: Willie Cauley-Stein, C Kentucky

HT: 7'0" | WT: 240 lbs | AGE: 21

Cauley-Stein's shot blocking and defensive versatility seem to be exactly what the Kings are looking to place next to DeMarcus Cousins. One of the wings (Justise Winslow, Mario Hezonja) are also possible.

7. Nuggets: Mario Hezonja, SF Croatia

HT: 6'8" | WT: 218 lbs | AGE: 20

Hezonja's athleticism and offensive ability should fit in well with the Nuggets' rebuild, giving them an offensive option who could be a central part of their team going forward.

8. Pistons: Justise Winslow, SF Duke

HT: 6'6" | WT: 225 lbs | AGE: 19

Executives continue to be lukewarm on Winslow's perimeter shot. His 41.8% three-point shooting was encouraging, but with his struggles from the line (64.1%) and inability to shoot off the dribble, they'd like to see more. One thing they're all-in on: Winslow's defense.

9. Hornets: Stanley Johnson, SF Arizona

HT: 6'6" | WT: 245 lbs | AGE: 18

Johnson falling here seems to be the perfect fit for the Hornets, as his defense would be a welcome addition to their rotation, and his perimeter shooting and decision making should help their offense.

10. Heat: Kelly Oubre, SG Kansas

HT: 6'7" | WT: 200 lbs | AGE: 19

Miami needs to decide whether to use this pick to find a player who can help them win now, or whether they should use this rare lottery opportunity to get a potential mainstay in their rotation. Oubre may not help them immediately, but has a lot of potential this late in the draft.

11. Pacers: Myles Turner, C Texas

HT: 6'11" | WT: 243 lbs | AGE: 19

The Pacers could use more depth on their front line, with the aging David West and the uncertainty around Roy Hibbert. Turner gives them some flexibility with his defensive presence and ability to step out on the perimeter offensively.

12. Jazz: Devin Booker, SG Kentucky

HT: 6'6" | WT: 206 lbs | AGE: 18

With the Jazz having their frontcourt locked down for the foreseeable future with Derrick Favors and Rudy Gobert, more depth on the perimeter, and floor spacing, could help them take the next step. Booker is one of the best shooters in the draft.

13. Suns: Frank Kaminsky, PF Wisconsin

HT: 7'0" | WT: 242 lbs | AGE: 22

Kaminsky's versatile offensive game should fit in very well with what the Suns are looking to do.

14. Thunder: Sam Dekker, SF Wisconsin

HT: 6'9" | WT: 230 lbs | AGE: 20

The Thunder have been trying to find some depth on the wings for a few years, a problem that got worse after trading Thabo Sefolosha last summer. Dekker's versatility could help Oklahoma City solve that problem.

15. Hawks: Trey Lyles, PF Kentucky

HT: 6'10" | WT: 235 lbs | AGE: 19

Adding more shooting to Hawks' lineup could be a scary proposition, and Lyles' diverse offensive game could thrive in their system.

16. Celtics: Bobby Portis, PF Arkansas

HT: 6'11" | WT: 242 lbs | AGE: 20

Portis has a lot of attributes that should make him a longtime contributor in the NBA, including rebounding, hustle, and face-up ability, which could fit in well with Boston's existing frontcourt lineup.

17. Bucks: Cameron Payne, PG Murray State

HT: 6'2" | WT: 180 lbs | AGE: 20

Point guard may not be an obvious area of need for Milwaukee after bringing in Michael Carter-Williams at the trade deadline, but adding Payne's offensive skill set would complement Carter-Williams well.

18. Rockets: Jerian Grant, PG Notre Dame

HT: 6'4" | WT: 204 lbs | AGE: 22

Houston needs point guard depth in the worst way, and Grant could bring a stabilizing presence for Houston off the bench.

19. Wizards: Kevon Looney, PF UCLA

HT: 6'9" | WT: 220 lbs | AGE: 19

Looney has a lot of physical attributes which make him very intriguing, and adding him to Washington's aging frontcourt could help them down the line.

20. Raptors: Rondae Hollis-Jefferson, SF Arizona

HT: 6'7" | WT: 220 lbs | AGE: 20

Hollis-Jefferson's incredible defensive potential could fill a big area of need for a Raptors team that struggled on that side of the court.

21. Mavericks: Delon Wright, SG Utah

HT: 6'5" | WT: 190 lbs | AGE: 23

Finding a long-term solution at the point guard spot after the Rajon Rondo experiment could be big for the Mavericks, especially one who can play defense like Wright.

22. Bulls: Tyus Jones, PG Duke

HT: 6'2" | WT: 190 lbs | AGE: 19

Adding Jones as a backup to Derrick Rose would give the Bulls some much-needed depth and stability at the position.

23. Blazers: R.J. Hunter, SG Georgia State

HT: 6'6" | WT: 190 lbs | AGE: 21

Should Portland retain LaMarcus Aldridge, Hunter's offensive game and skill level could give them more depth to make another run.

24. Cavaliers: Justin Anderson, SG Virginia

HT: 6'6" | WT: 227 lbs | AGE: 21

Anderson credits his improved shot to better shot selection and decision-making. If that drastic improvement holds true, Anderson's defense could make him a very valuable piece to a puzzle.

25. Grizzlies: Rashad Vaughn, SG UNLV

HT: 6'6" | WT: 210 lbs | AGE: 18

Vaughn's stock has been rising fairly steadily of late, and Memphis could really use some shooting here. If R.J. Hunter doesn't fall, Vaughn could be a nice option.

26. Spurs: Montrezl Harrell, PF Louisville

HT: 6'8" | WT: 240 lbs | AGE: 21

Harrell's offensive game still needs some work, but he has the type of size and hustle to be a contributor on the defensive end.

27. Lakers: Terry Rozier, PG Louisville

HT: 6'2" | WT: 200 lbs | AGE: 21

If the Lakers go big with their first pick they'll need some perimeter shooting to complement that. Rozier has a lot of talent on that end of the court.

28. Celtics: Robert Upshaw, C Washington

HT: 7'0" | WT: 250 lbs | AGE: 21

Boston could really use some shot blocking on their front line, and Robert Upshaw, who was kicked off of Fresno State and Washington, is one of the best in the draft.

29. Nets: Christian Wood, PF UNLV

HT: 6'11" | WT: 220 lbs | AGE: 19

Wood's shot blocking (2.7 per game) and perimeter shooting ability could fit in well in Brooklyn, whether or not they keep Brook Lopez (player option for 2015-16) around long-term.

30. Warriors: Jarrell Martin, PF LSU

HT: 6'9" | WT: 235 lbs | AGE: 20

Golden State's shooting and floor spacing should allow the athletic Martin a chance to shine.
