Zibanejad, who agreed to terms on a five-year, $26.75 million contract (average annual value of $5.35 million) on July 25, is expected to take Stepan's spot as the No. 1 center. Hayes is expected to move up to be the No. 2 center after playing in the middle on the third line for most of his first three seasons.
Stepan averaged 55 points in the past four seasons and played in all situations. Zibanejad and Hayes have never reached 55 points in the NHL, but they gave Vigneault confidence they could do that and more last season.
Zibanejad got off to a terrific start with 15 points (five goals, 10 assists) in 19 games before breaking his leg on Nov. 20. He had 22 points (nine goals, 13 assists) in his final 37 games and showed flashes of being a future No. 1 center in the playoffs. His issue has been inconsistency in his aggressiveness. He's occasionally too passive.
Hayes had an NHL career-high 49 points (17 goals, 32 assists), showing the growth the Rangers needed to see after his production and drive tailed off during the 2015-16 season. Hayes, who is 6-foot-5 and 215 pounds, hasn't always used his big body and long reach to his advantage.
