Perhaps Derrick Rose had his epiphany watching fellow Chicago native Iman Shumpert leap to the Garden’s pin-wheeled ceiling Tuesday night to slam home a put-back dunk — the slam of the playoffs. Rose and Shumpert tore their ACLs on the same night nearly 13 months ago. Shumpert returned Jan. 17, but this was the first moment it appeared Shumpert had all his athleticism back. Rose may finally suit up and make his season debut tonight for Chicago against the Heat. Maybe Shumpert’s continued rousing success and spectacular slam has ignited Rose. They played high school ball during the same period, though their schools never met. “I’ve been asked about it a lot,’’ Shumpert said. “The Bulls have been doing a great job playing without him. I’m definitely reminded by it every day. “[Bulls fans] are a little surprised, but I think they understand, because Derrick Rose is a franchise player. He’s got a totally different situation than I have.” Shumpert, a defensive demon, had a disappointing start to his comeback. But since April he looks back in his solid rookie form. In fact, he’s been better, with a more reliable 3-point shot. Shumpert is defending the Pacers’ Paul George, who committed seven turnovers in Game 2. Less than two weeks ago, Shumpert said the Knicks trainers told him his full athleticism won’t return until next season. Shumpert proved them wrong Tuesday. “I’ve seen it quite a few times,” Shumpert said of the replays. “I can’t take it with me into the game Saturday, so I’ve got to sort of forget about it. But I’m going to continue to attack the glass.”
