LAKE BUENA VISTA, Fla. (AP) — LeBron James never took appearing in the postseason for granted. He never counted on playing even one playoff game in a season, even long after it became viewed as a failure if he didn’t play for a title. The NBA is hard, he could just make it look easy. And he believes this postseason, his first in two years and the most unusual in league history, will be his most challenging yet. James says the unusual circumstances of playing at Walt Disney World make this his toughest postseason yet. His Los Angeles Lakers start it Tuesday against the Portland Trail Blazers.
