What do the Rangers want, and where can they find it? They could answer the first question easily enough ahead of Tuesday's home game against the Philadelphia Flyers. But the second question baffled them. Enlarge This Image What the Rangers want is more scoring from their second, third and fourth lines. That was why Saturday they tentatively signed the 38-year-old free-agent forward Jason Arnott, who scored 17 goals last season for the St. Louis Blues. But the deal fell through Sunday when Arnott failed a physical, so it was back to the drawing board for the 2-3 Rangers. Their top line of Marian Gaborik, Brad Richards and Rick Nash has 19 points. The rest of the team has 18. "We can't just rely on that one line," Coach John Tortorella said after practice Monday. "If that line struggles, we have no chance. We need to get other people going."
