James wasn't quite the shooter Bird was, but let's not pretend Bird was Steph Curry from three either. Bird only had 6 seasons above 40%, but he was also under 30% four times. James eclipsed 40% just once, but only his rookie year was he below 30%. Bird was obviously a beter outside shooter, but it isn't nearly the gap people on here make it out to be, but here is where it gets really interesting. Bird had just two seasons above 60% in TS%, James has had four such seasons already.
Bird is a better rebounder no question, but there were a lot more possessions in the 80's than they are today and when you look at TRB%, Bird is about 4% better i.e. he grabbed 4% more of the available rebounds. However, passing there is a significantly larger gap where James is about 10% better than Bird. In fact James' rookie year he was 27.8%, Bird was only better than that one time (and that was about 6% lower than James' career average). They are nearly equal in steal, block, and turnover percentage. James career average in PER is higher than Bird's best season.
So even with the lower possessions, James has higher career highs in all but rebounds and better efficiency stats basically across the board (again except rebounds). James not only has had a longer career, he has had a statistically greater career, with more awards and accolades. Only Celtics fans still put Bird above James and even that list is shrinking as evident by this thread (and a few others).
James is the greatest SF in NBA history.
