Plan A apparently could be making a comeback for the Miami Heat, at least temporarily. What appeared unlikely after stifling Atlanta Hawks guard Trae Young into submission in the first round of the playoffs stands as a second-round option, as well. James Harden, say hello to Erik Spoelstra’s (not-so) little friends. With MVP contender Joel Embiid sidelined for at least the start of the best-of-seven Eastern Conference semifinal series, the Heat again are presented with the opportunity to create singular misery, after limiting Young to 15.4 points on .319 shooting in the opening round. “In the past series, we were able to defend an elite guard,” Heat guard Tyler Herro said, “and Philly’s got Harden and [Tyrese] Maxey, who are great guards. “So [it means] being able to take our experience from that in the past series and applying it to this next series, if Embiid doesn’t play.” The difference is Young is a 23-year-old neophyte.
