12) John Havlicek
Celtics icon John Havlicek often gets overlooked in NBA history, even though he was a 13-time all-star and won eight, count em, eight championships playing with Bill Russell. During his top-tier career, Halvicek was a two-way superstar, though we'll stick to offense when talking about him for obvious reasons.
Playing in the early 1960s until the late 1970s, he played the entirety of his career without the 3-point line, which made it much harder for a wing, even an elite one, to drop 50 points. You either had to be a super-efficient scorer, take a lot of shots, or make a lot of free throws. Halvicek was efficient for his era and took plenty of shots as a result of his averaging more than 40 minutes per game five times in his career.
He also averaged at least 27 points per game in consecutive seasons but has a comparatively low career high of 43 points. On the flip side, without his big scoring performances, he was more consistent as an offensive player, which is equally valuable.
