LeBron James missed once, then again, whiffing on two easy looks at the rim that could have left Miami shaken. Like a good teammate, Dwyane Wade swooped in for the saving tip, preserving the lead and keeping the Heat's amazing win streak rolling. James scored 27 points and the Heat became the fourth team to win at least 20 consecutive games in a season, beating the Philadelphia 76ers 98-94 on Wednesday night.
