With Enes Kanter set to return from a three-game absence, the questions as to what the Knicks will do about their logjam at center continue to loom. Primary backup Kyle O’Quinn earned three straight starts as Kanter sat with back spasms, while Willy Hernangomez got more than garbage time and Joakim Noah finally made his debut. The 23-year-old Hernangomez, a member of the All-Rookie first team last season, averaged five points and 6.7 rebounds in 19 minutes during the stint without Kanter. Noah, who was suspended for the first 12 games and inactive for the ensuing seven, received his first three minutes in a loss Monday to the Trail Blazers, scoring two points, blocking one shot, grabbing one rebound and committing one careless foul. Jeff Hornacek was vague about how the rotation will take shape. “Jo did good,” he said. “We do have four guys at that [spot]. I’ve talked to him about it, how the rotation is going to go. He’s just going to continue to work on his game and always be ready.” Asked if he had given any thought to sending Hernangomez to the G League, Hornacek said: “I don’t think we’ve discussed that so far. As we move forward, if we’re back with Enes and Kyle, and maybe even Jo occasionally, we are going to need to figure that out. I don’t know if we can always dress four bigs.”
