There are many issues beguiling the 3-8 Knicks, but the referees’ harsh treatment of Carmelo Anthony and coach Mike Woodson’s harsh treatment of Iman Shumpert are two of the biggies. On his ESPN Radio show Thursday, Woodson defended how he handles Shumpert, meeting with him Thursday, while lobbying to officials Anthony isn’t getting superstar calls. Woodson said he believes Anthony’s final shot in regulation Wednesday night — a 12-foot turnaround over Paul George — could have been called a foul as contact ensued. The Knicks lost in overtime, 103-96, for their fourth straight loss with a four-game road trip ahead, starting in Washington on Saturday before hitting the West Coast. Asked if Anthony is not receiving calls normally associated with a superstar, Woodson said, “Absolutely. I’m not going to shy away from that either. Melo gets hit more than ever. If you go to that overtime game, we were down six. Melo got whacked coming across the middle and there was no call. “I’ve been at this thing 30 years,’’ Woodson added. “Sometimes I’m starting to wonder what’s a foul and what’s not a foul. He’s a gifted offensive player who has a knack to draw contact and get fouled. Sometimes he comes up empty a lot of times.’’ Anthony does not do himself favors with the officials. Since last season, when he was the league leader in technical fouls, he has developed a penchant for railing at the referees on the court.
