Brian Leetch is not only one of the best Rangers of all time, but he had the best rookie year of any player in history.
In the 1988-89 season, in just 68 games, Leetch scored 23 goals and had 48 assists.
Leetch won the Calder Trophy as the league's best rookie and was named to the All-Rookie team.
Leetch, of course, followed that up with a wonderful career, scoring 247 goals and 781 assists. He won the Norris Trophy twice, and was a First Team All-Star twice. His number is retired.
From the beginning, Leetch simply dominated. His offensive gifts and his defensive prowess have not been replaced since he was traded during the 2003-04 season.
