Spurs are at a tipping point no NBA team wants to be in with Harrison Barnes

For the first time in a decade, San Antonio Spurs forward Harrison Barnes finally came off the bench after 350 consecutive starts. Coach Mitch Johnson made the long-awaited call prior to their game against the Charlotte Hornets.

That opens up possibilities for the Spurs as well as raises questions about Barnes' future. His declining play has been hard to watch since it wasn't that long ago that he was "Mr. 100%." Now, it's surprising when he actually hits a three.

With Julian Champagnie now starting—presumably going forward barring a trade—Barnes may soon be on his way out of town

Harrison Barnes may not have a future with the Spurs

Barnes coming off the bench could solve the Spurs' issues, with Champagnie being a better player on both ends. It also limits Barnes' minutes. Honestly, he should probably only be playing around 20 minutes a game.

Barnes being benched and seeing his minutes cut probably shouldn't instill confidence. Hopefully, fewer minutes could limit the wear and tear on his body and fully lead to more consistent play. He should also benefit from playing against second units.

If he doesn't, well, then the Spurs could simply let him walk in free agency or even look to trade him at the trade deadline.

His $19 million expiring contract is obviously useful in a potential trade. Even if the Silver and Black don't trade him, they could still target another power forward at the trade deadline.

The Spurs appear to be moving on from Barnes in real time

A player such as Bobby Portis Jr. would be an upgrade over what Barnes has provided, and the Silver and Black should absolutely explore their trade options. Even if they don't ultimately make a big trade to bring in a power forward, they could still cobble together enough minutes at the four.

Particularly with the Spurs also having Luke Kornet. He could further minimize Barnes' role if he can't snap out of his month-long free fall. That at least gives them options. Credit to Johnson for trying to solve their biggest flaw even when it means benching a well-liked veteran.

What happens next will depend on Barnes' play. If he can bounce back, then San Antonio will be better for it. If he can't, then he may be playing his way off the Spurs.
