NBA is officially running out of time to stop Spurs' newfound offensive attack

The NBA regular season is officially over, and the San Antonio Spurs finished strong. The 62-win Spurs have been arguably the best team in basketball since February 1st, going a staggering 30-4 in their last 34 games.

What has been fueling their success is their backcourt of the future: Stephon Castle and Dylan Harper. Both players have leveled up as the season has progressed while helping the Silver and Black at the same time.

Harper ranks as one of the most efficient scorers in the paint but has begun draining threes at a reliable rate. The same can be said for Castle, who has been an above-average shooter over the last two months and counting.

Having two poor 3-point shooters suddenly start knocking down threes has given San Antonio's offense an unexpected jolt.

Stephon Castle and Dylan Harper are giving the Spurs a huge jolt

Castle has been San Antonio's second-best player this season, while Harper has been the fourth-best Spur. What has set the Silver and Black apart is that both are so young that they are improving in real time.

Remember when Castle led the league in turnovers per game over the first two months of the season? Well, that number has dropped like a stone, with him only turning it over 2.7 times per game over his last 30 games.

Better still, his assists are up, with him averaging 7.1 dimes. Factor in his hot shooting and his elite defense and he is quickly becoming a well-rounded weapon on both sides of the ball.

Harper is in a similar boat. He was already one of the best in the NBA at getting to and finishing at the rim. However, him drilling threes adds a new layer to both his and the Spurs' games.

Castle and Harper being able to knock down threes increases their ability to play off-ball. In turn, that makes the possibility of a three-guard lineup with Fox, Harper, and Castle much more realistic. It also increases San Antonio's overall spacing and, therefore, their offensive efficiency.

Since February 1st, San Antonio boasts the second-ranked offense in the NBA. Prior to that, they ranked seventh in offensive efficiency. Considering they already had a top-3 defense, having their offense improve dramatically seemingly overnight explains them going 30-4 in their last 34 games.

Entering the season, Castle, Harper, Fox, Keldon Johnson, and Jeremy Sochan were the five players that were all expected to play big minutes but couldn't space the floor.

That hasn't been the case with Sochan barely playing before being waived. Meanwhile, Johnson is shooting above league average, and Fox has been streaky, while Castle's and Harper's three-balls are beginning to come around.

With the playoffs almost here, San Antonio needs both Harper and Castle to continue shooting the leather off the ball. If they can, then the Silver and Black's recent offensive explosion could help propel them to a championship this season.
