Cavaliers star LeBron James has turned serious with the playoffs upon us.

Cleveland will begin their postseason run on Saturday when they host Chicago, a team that beat them twice during the regular season.

"We're ready for the challenge," James said. "I think [Joakim] Noah's a really good player. He's a really good talent. But, you know, he asked for us a couple weeks ago and he got us. So we're ready. It's a different monster they're going to be playing against on Saturday."

The Cavaliers are determined to deliver a championship to Cleveland, a city that hasn't had a pro sports title since 1964.
