Cleveland Cavaliers superstar LeBron James says he's committed to staying longer in Cleveland and helping the team with an NBA championship.

Speaking to ESPN, the former Miami Heat star says he is not planning to enter free agency again next summer despite a clause that allows him to do so next year. "My No. 1 goal is to win a championship here; it'd be the greatest achievement in my life," he said. He also clarified that he's in for the long haul, adding: "I don't plan on going nowhere. I don't have the energy to do it again."

James was in his hometown of Akron, Ohio for his annual charity event for school children. His welcome home rally was participated in by more than 25,000 people. He had recently signed a two year deal with the Cavs expected to be worth around $42 million, with the anticipation that there would be a dramatic jump in the league's salary cap and max-contract level in 2016 with new television deals expected to kick in.

The Cavs have been very busy this summer, improving their roster in a bid to help James fulfill his promise. They have signed shooters Mike Miller and James Jones, former Heat teammates of James, to help provide outside artillery and unclog the lanes for LeBron and All-Star guard Kyrie Irving.

More importantly, the Cavs have reportedly agreed on a trade in principle to send this year's top draft pick Andrew Wiggins and sophomore forward Anthony Bennett for All-Star forward Kevin Love. Should the trade push through, the team will have arguably the most talented trio in the league in James, Love, and Irving.

"Even with the veterans we've brought in, even if we're able to acquire Kevin Love two weeks from now, it's still going to be a process," James said. "I know that firsthand. It was a process when I was in Cleveland. It was a process in Miami. It's going to be a challenge."
