Let's be fair now.
Kareem and especially Magic never had to face defenses or defenders that the NBA employs today. Not even close. Not remotely. If they had to face modern defenses, those 50-60+ FG% seasons would significantly reduce. They would still be great, but to compare their consistency to Kobe's consistency is partly unfair due to the considerably superior defense the NBA plays these days.
When I think of consistently, I think of a guy who at times hits all the shots he should, and other times misses most all of the shots he should. I don't see that being a major issue with Kobe. From what I see, his issue is that he gets hot at times and hits shots he shouldn't be taking, and then starts missing shots he shouldnt be taking. But generally, I don't see Kobe having a lot of nights where he is just missing open 18 footers or anything like that, shots that he should rarely miss. His issue stems more from incredibly poor shot selection, than from consistency, imo.
I don't disagree at all that Magic is a better natural floor leader than Kobe is, but Kobe is certainly capable of being a leader when need be, but his ability to put a team on his back and carry them, is a quality that Magic doesn't come remotely close to having on par with Kobe. Magic's style might have worked great in the 80s when no one played defense and everyone was playing SSOL style basketball, but in today's NBA, I'll take Kobe's ability to put a team on his back, put the clamps on the opposing teams best wing player while simultaneously breaking down elite defenses.
