There will be no halfway the balance of the season for the Miami Heat. It either will be all in, or out of uniform. That was the consensus Friday when coach Erik Spoelstra and his players discussed how they would handle the balance of the regular season, with little in the way of meaningful games remaining on the schedule. "We'll continue to try to improve our game, get ready for the playoffs, and we'll manage everything on a day-to-day basis from here on out," Spoelstra said in advance of Friday's game against the New Orleans Hornets at New Orleans Arena. "And we've struck that balance before, in the past. There's not a perfect formula to it, but we'll evaluate everything while we're trying to compete and get better." At Friday morning's shootaround, that meant holding out point guard Mario Chalmers and power forward Udonis Haslem because of nagging ankle injuries. Forward LeBron James said he would appreciate a break over the final two-plus weeks.
