The Knicks are putting together quite the tag team at center. After starting center Enes Kanter struggled, Kyle O’Quinn came to the rescue Monday night with a monster outing and played the final minutes of crunch time. Getting key rebounds in the final two minutes, O’Quinn finished with a healthy double-double — 15 points, 12 rebounds and five blocks in 21 minutes. O’Quinn was plus-14 — a team high. By comparison, Kristaps Porzingis had a career-high 38 points but was even on the plus/minus scale. When Kanter came aboard in the Carmelo Anthony trade, everyone figured O’Quinn would be out of the rotation, but he has beaten out Willy Hernangomez for backup minutes. Hernangomez got a cup of coffee Monday, getting 3:07 of playing time, but mostly has been out of the rotation. “I”ve been wondering about my role my whole career,” O’Quinn said. O’Quinn is the defensive enforcer of this platoon.
