San Antonio Spurs Embracing Change, Usher in New Era with LaMarcus Aldridge

It's the stuff NBA free agency is made of. And in this case, it may well be the next chapter in one team's bid to prolong a dynasty.

Free agent LaMarcus Aldridge declared his independence from the Portland Trail Blazers on Saturday, returning to his home state and just one hour south of his alma mater University of Texas at Austin.

Yahoo Sports' Adrian Wojnarowski first reported a four-year maximum deal with the San Antonio Spurs, which Aldridge himself confirmed.

"

I'm happy to say I'm going home to Texas and will be a Spur!! I'm excited to join the team and be close to my family and friends.

— Lamarcus Aldridge (@aldridge_12) July 4, 2015"

The contract assures that the Spurs will boast a one-two punch of Aldridge and reigning Defensive Player of the Year Kawhi Leonard for the foreseeable future. On Wednesday, Wojnarowski reported Leonard agreed to a five-year, maximum deal to remain with the club that acquired him on draft day in 2011. 

The Spurs have been in the winning business for decades, particularly since Tim Duncan joined and eventually replaced center David Robinson as the face of the South Texas franchise. So it's only fitting that the championship window open a little wider as Duncan's career approaches its inevitable end.

Head coach Gregg Popovich will reportedly stick around to oversee the Duncan-Aldridge transition, just as he managed the Admiral's final years.

San Antonio has historically built through the draft, using free agency to fill out rosters with unheralded names or veterans on the wrong side of their primes. Not this time.

General manager R.C. Buford may not be done yet, either.

And guys such as David West are suddenly obtainable given the organization's embarrassment of riches. That's where much of Aldridge's value really lies, as a building block and recruiter who can keep San Antonio relevant for another generation.

He'll be a beast on the floor, too. Still in the prime of his career and skilled enough to age gracefully, Aldridge appears to be an ideal cohort and eventual replacement for the man who's anchored this team's interior since 1997. Duncan recently confirmed to the San Antonio Express-News that he'll return for at least one more season.

They're different players, to be sure. Though Duncan has a steady enough mid-range game, Aldridge is a far more prolific (and productive) pick-and-pop weapon, particularly at this stage of their respective careers. Aldridge also boasts an array of Nowitzki-like moves in the post and when facing up on the wing. He's an incredibly polished shooter despite his 6'11" build.

For his part, Duncan is the better rim protector, and he'll likely focus much of his effort on the defensive end now that Aldridge is around to shoulder more of the offensive burden. Duncan and Aldridge are certainly versatile enough to coexist, if not perfectly complementary fits with one another.

San Antonio now owns perhaps the most formidable frontline in the game, a trio of Aldridge, Duncan and Leonard that's capable of controlling the paint, spacing the floor and exerting all kinds of two-way dominance. It's a scary thought for the rest of the league, even a Southwest Division (and Western Conference) that's stacked with would-be contenders.

The even scarier reality is that this team is well-prepared to remain in the hunt even after Duncan moves on.

By retaining talent (Duncan for now, Leonard and shooting guard Danny Green, as ESPN.com's Chris Broussard reported) and adding Aldridge, the Spurs have become an unholy combination of the Memphis Grizzlies and reigning champion Golden State Warriors. The former's one-two punch of Marc Gasol and Zach Randolph isn't unlike what we should expect from San Antonio's new interior duo. The latter's predilection for spacing and pace is a hallmark in Popovich's offense.

It may take a little time for Aldridge to adjust to his new teammates and system. He'll see more of his opportunities come through the natural flow of a Tony Parker-run offense, less from isolation and post-up situations. And the Spurs will have to adjust to Aldridge, as well. He likes to hold the ball and size up defenders, and San Antonio hasn't been that kind of team for a while now, preferring instead to keep the ball moving.

But even with a customary jelling period, this team reasons to be awfully good in short order. Aldridge will be 30 when the season starts and should have plenty of gas in the tank. He's coming off a campaign in which he averaged a career-high 23.4 points and a respectable 10.2 rebounds per contest, and his post game has improved fairly dramatically over the course of his nine-year career. Few big men can score in so many ways.

At his best, Duncan was certainly one of them. Now he'll take a backseat—and likely a significant pay cut.

Affording Aldridge wasn't easy for the Spurs, who last week traded center Tiago Splitter to the Atlanta Hawks to create the requisite cap space. The organization also passed on signing sharpshooting swingman Marco Belinelli, who recently agreed on a three-year pact with the Sacramento Kings, per ESPN.com's Ramona Shelburne.

Costly, yes—but also well worth it.

The Spurs are set to contend this season and well into the future. An Aldridge-led core will attract other free agents, and the Spurs have a wealth of talent stashed overseas, including this summer's draft selection Nikola Milutinov and 2013 first-rounder Livio Jean-Charles. Buford and Co. have—as always—done a masterful job of keeping this team stocked with assets and skilled veterans alike.

In retrospect, it's not terribly surprising that Aldridge would fancy himself piloting such an operation. This is a model franchise whose titles speak for themselves.

All Aldridge had to do was listen. And he ultimately liked what he heard.

After team representatives initially met with Aldridge in Los Angeles, Popovich met with him a second time over lunch, as ESPN.com's Marc Stein reported. The message? 

Becoming the heir to Duncan's throne.

Those are big shoes to fill, but Aldridge will have some help from a still-talented roster and one of the game's great front office-coaching staff combinations. It's the situation he wanted—and the one San Antonio needed.
