This is how dynasties end, folks. Not with a championship parade, but with a play-in tournament loss and a coaching legend walking away.Multiple sources are telling us that Steve Kerr is not expected to return to the Golden State Warriors barring what one source called "renewed faith" in the franchise's direction. And after what happened this season, you can understand why that faith might be gone.Let's talk about what Kerr built in the Bay Area. Four championships. 73 wins in a single season. The Death Lineup. He didn't just coach the Warriors - he revolutionized how basketball is played. Small ball, pace and space, three-point revolution - that all came from Kerr's playbook.But this season? This was supposed to be one last run at glory. Instead, it became a season of torment, as one report put it. Jimmy Butler missed 44 games with a torn ACL. Stephen Curry was out 39 games with runner's knee. The roster that was supposed to contend for a title never got healthy enough to find out if it could.Here's what tells you everything about where Kerr's head is at: "They could offer Steve $25 million a year, and I doubt that alone would make a difference," a league source said. This isn't about money. This is about a coach who came in wanting one more championship and instead watched his team fall apart.A decision is expected within days, not weeks, and unless something dramatic changes, one of the greatest coaching runs in NBA history is over. The Warriors' dynasty - the Splash Brothers, the championships, all of it - is coming to an end.That's what sports is all about, folks. Nothing lasts forever, not even greatness.
