It's Weight. Then Savard. Then Stepan. They draft one or two good centers a decade. Plus in general these guys score the majority of their points for other franchises, like Weight and Savard because the Rangers trade them. At least Stepan played here for many years.
oh and Dave Gagner too I forgot him, but again he barely played 80 games for the Rangers and didn't become a regular until he went to Minnesota and scored 40 goals twice.
Rangers over the last 30 years always seemed to be trading for or signing as free agents their scoring centers rather than drafting and developing them. Messier, Gretzky, Ferraro, LaFontaine, Nedved, Lindros, Nylander, Rucchin, Cullen, Richards, Brassard, Zibanejad, etc.
