Wayne Gretzky-Is he the greatest scorer of all time?

Yeah, there's a reason why he's got the nickname "The Great One". 894 goals, 1963 ists=2857 points. He's the greatest scorer by like 90 goals but he'll still be the greatest scorer without his goals. His 1963 ists are more than Mark Messier's 1887 points (2nd all-time scorer).
