The Knicks’ net rating (estimated point differential per 100 possessions) in the fourth quarter over their last 10 games is -34.9 — last in the NBA, with the Rockets (-21.4) the next closest. Their fourth-quarter offensive rating (estimated points scored per 100 possessions) in that span is 85.5, well below the next-closest team, the Trail Blazers (100). “I feel like we’re in a position right now where we are down two or down three, teams get on a run, it’s like, ‘Oh s–t, again,’ ” Fournier said. “Maybe just a good win would help us more, more confidence would help.” Having a veteran point guard to run the offense late in games — and therefore instill some of that confidence in crunch time — would also help.
