2015 NBA Draft Combine Prospects San Antonio Spurs Must Watch Most Closely

The San Antonio Spurs should be paying close attention to the 2015 NBA Draft Combine, since the team's roster is almost certain to be shaken up this offseason.

According to HoopsHype, just five players are currently under contract. Tim Duncan and Manu Ginobili will both need new deals if they don't retire, while Kawhi Leonard and Danny Green highlight the pair of expensive free agents.

But the franchise must be mindful of potentially replacing its role players, considering Aron Baynes, Marco Belinelli and Cory Joseph could be on the way out.

The combine is a terrific place for San Antonio to start that process. The Spurs should have their eyes on a handful of talented prospects who fill roster needs, fit the system and will realistically be available at 26th overall in the draft.

Whether Manu Ginobili retires in the coming days or waits until next year doesn't matter; San Antonio needs to groom a replacement for the future Hall of Famer. And if Joseph follows the money trail or chases a promise of more playing time, the Spurs will no longer employ their backup plan, either.

That's where Delon Wright comes in.

Though not a spectacular offensive weapon, his ability to change speed and direction keeps a defense off balance.

Wright needs to work on finishing at the rim, but he's shown a knack for attacking the basket and drawing fouls. The point guard attempted at least five free throws per game during two seasons at Utah, connecting on 81.4 percent of the freebies.

San Antonio could pair Wright, a tremendous defender, with three-point specialist Patty Mills, since the Australian won't be confused as a ball-stopper.

Justin Anderson, Small Forward

The lack of depth at small forward plagued the Spurs when Kawhi Leonard sustained an injury and missed extended time. Danny Green and Marco Belinelli have typically picked up the slack, but if San Antonio cannot re-sign Green, the defense will be in serious trouble when without Leonard.

Justin Anderson made a name for himself at Virginia on the defensive end, hassling perimeter options and frustrating opponents with his length.

As a junior, the 6'6" small forward added a particularly useful component to his arsenal: offense. Anderson drained 45.2 percent of his triples last season, a 15.8 percent rise from his sophomore campaign.

Anderson would fit nicely alongside Kyle Anderson in the future, since the latter's court vision and passing ability could capitalize on the former's range. Kyle doesn't yet have a true position—maybe a point guard, shooting guard or small forward—but Justin would ease that dilemma, too.

Regardless, it's easy to get carried away with Anderson's potential, but an off-the-bench three-and-D swingman is the role San Antonio would likely ask him to occupy.

R.J. Hunter, Shooting Guard

He hit a clutch three-pointer to win an NCAA tournament game. It's something kids dream about accomplishing. It was amazing. It epitomized what March Madness is about.

It also meant little for R.J. Hunter's NBA prospects.

Nevertheless, his fearless shooting nature must be an appealing element, assuming Hunter relinquishes some of the reins and willingly joins a team-oriented system. He only connected on 29.8 percent of his triples, but that number should rise when he isn't the focal point of the offense.

He protected the ball well, committing only 2.2 turnovers per outing despite controlling the rock on a majority of Georgia State's possessions.

The problem with Hunter as a potential San Antonio draftee is he might simply be Patty Mills 2.0, in which case the Spurs presumably would pass. But that shouldn't stop them from considering Hunter if there's a run on guards before No. 26.

Norman Powell, Shooting Guard

Cory Joseph was a valuable reserve, but a terrific stretch in the 2014-15 campaign as Tony Parker's injury replacement might mean San Antonio cannot afford to keep the Texas product.

While Norman Powell wouldn't be a replica, his biggest strength matches that of Joseph: attacking the basket. According to Hoop-Math, Powell tallied a 57 percent mark at the rim, which is where he attempted about half of his total shots last season.

And similar to Joseph, Powell displayed plus-defense—though unsurprisingly not as refined as the four-year pro—snatching 1.8 steals per contest.

Powell could be an emergency plan at the end of Round 1 if the top defending or shooting guards have been selected.

Michael Frazier II, Shooting Guard

Marco Belinelli has carved out an eight-year NBA career by being a lights-out three-point shooter, though he might be looking for his sixth home in season No. 9.

But if the Italian can succeed in San Antonio, so can Michael Frazier II.

A 43.2 percent shooter from long distance at Florida, Frazier would be an intriguing second-round option—especially if San Antonio tabs a non-shooter first. Although his numbers dipped in 2014-15, it was largely the product of Frazier shifting from complement to feature.

The Spurs would allow him to roam the perimeter as a trifecta technician and potentially make Frazier a catch-and-shoot terror once again—even if he can't play much defense.
