On the night the Clippers got everyone back for the first time this season, the Heat was without two of its top four scorers. Chris Bosh missed his second game in a row with flu-like symptoms, and Ray Allen was sick as well for Friday’s marquee game against the Los Angeles Clippers. Bosh, Allen and Dwyane Wade missed Friday morning’s shootaround because of the flu, but Wade, despite appearing under the weather, was healthy enough to play. “We thought we would throw them a similar curveball,” Heat coach Erik Spoelstra joked Friday morning. “That’s the NBA.” While the Heat struggled to fill out its roster for the nationally televised game, the Clippers enjoyed a benchmark game in Miami. For the first time this season, the team had its full complement of players available. Point guard Chris Paul, who hadn’t played since Jan. 21, returned from a bruised kneecap. Veteran guard Chauncey Billups, who had only played in three games before Friday, was activated after suffering from an inflamed tendon in his foot during the first half of the season. Forward Blake Griffin, who had missed two games in a row with a hamstring injury, returned to the starting lineup. And scoring maven Jamal Crawford (shoulder) also played. The Clippers, who were third in the Western Conference, 4 1/2 games behind the Spurs entering Friday, went 3-6 with Paul out of the lineup.
