The Miami Heat's maintenance program is starting early this season, second-game early. A night after an uneven 5-of-13, 13-point performance in the Heat's season-opening victory over the visiting Chicago Bulls, guard Dwyane Wade was held out of Wednesday's game against the Philadelphia 76ers at the Wells Fargo Center. For the Heat and Wade it is the continuation of a delicate dance that saw Wade limit his offseason basketball work and then sit out three of the Heat's eight exhibitions in the wake of the knee issues that limited him during last season's playoffs. "That's really part of the plan," coach Erik Spoelstra said of Wednesday's decision. "It's not necessarily our rule that he won't play back-to-backs. It's just been a long week in terms of our preparations. His knee is a little bit sore, but nothing dramatic of a major concern. We're just going to be proactive with it." Spoelstra said the decision was made in consultation with Wade and trainer Jay Sabol. "It was something that our trainers and the coach came to me with, and they said it was early in the season and they just wanted to be precautious about it," Wade said before Wednesday's game. "Like I said during preseason, take things day to day and make a decision."
