Frank Ntilikina managed to wrap a typical rookie season all into one night Monday at the Garden. After shooting 0-for-4 with a turnover in the first half, the Knicks point guard was benched for the entire third quarter. He showed some life in the fourth as the Knicks mounted a comeback, but it was hardly enough in a 103-91 loss to the Trail Blazers. “As a teammate, you see your teammate get in the game and the game is not going that good,” Ntilikina said. “So you do as much as you can off the court. I was on the bench, so I talked to the guys.” Ntilikina finished shooting 3-of-11 with one rebound, one assist and one turnover as his recent stretch of tough games continued. The French guard’s struggles were captured late in the fourth quarter, when he rushed a deep two-point field goal on the fast break. It clanked off the rim as the Knicks’ comeback was taking its last gasps. “Guys are trying to make plays and trying to get us back in the game,” coach Jeff Hornacek said. “We had a little momentum, but that’s where we have to learn who our shooters are. And Frank can make that shot. … He felt like he could make that, and that’s a lesson we’ll have to learn.”
