The Miami Heat swept the season series against the Cleveland Cavaliers on Tuesday night for the third consecutive campaign.

LeBron James, who can become a free agent in the offseason, was asked about potentially returning to the Cavaliers one day.

"As of right now, it's too hard for me to think about,'' James said. ''We have 20 or less games before we gear up for no sleep for two months, hopefully. So for me to try and take my mind somewhere else when I know what's on its way is almost impossible.''
