It was a favored expression of Pat Riley, one he used frequently to emphasize the importance of the dirty work of the NBA’s blue collar laborers. “Rebounds equal rings.” And it was an expression everyone in basketball knew. “I never heard that,” Knicks center Enes Kanter said. “Seriously. But I like that. A lot.” OK, well almost everybody knew it. Kanter, who entered Wednesday’s game against the Raptors at the Garden as the NBA’s 10th best overall rebounder, showed just how much he appreciated it by grabbing … four rebounds, equaling his lowest total of the season. But Kanter impacted the Knicks’ 108-100 victory in other ways — like with his passing. Kanter had a season-high five assists — two of them coming at a critical point. The Raptors had fought back from 20 down and were within 94-88. Kanter threw a point guard-like lead pass to Kristaps Porzingis, who notched a three-point play. Next, Kanter foiled a double-team and found Porzingis on the right baseline for a jumper and it was 99-88 with 4:54 left.
