Observations and other notes of interest from Thursday night’s 129-101 victory over the Philadelphia 76ers: – Yes, the victory keeps the Heat alive for No. 6 in the East. – And direct entry into the best-of-seven first round of the playoffs. – And the victory probably doesn’t matter. – Because regardless of any other results going forward from the Heat or the Nets, if the 76ers lose Sunday in Brooklyn, then the Nets are Philadelphia’s first-round opponent. – And the Heat are in the play-in, where one or two losses and the season is over. – In other words, expect to see Dewayne Dedmon starting at point guard for Philadelphia in Brooklyn at Barclays Center on Sunday afternoon, if that is what is needed for the 76ers to avoid the Heat. – Yes, stranger has happened. – And, yes, a Nets win before Sunday (on Friday at home over Orlando) or a Heat loss in their final two (at Washington, home against the Magic), would make Sunday’s 76ers-Nets moot. – But we’re at a time of season when manipulation is rampant. – And the 76ers still are in control of who gets No.
