Bias was never on the same planet in terms of Lebron as a passer or distributor, which is what makes Lebron so special. He also was a lot smaller - he played at about 210 pounds, whereas Lebron is closer to 260. Bias was a big scoring wing and a good one, but Lebron is some unholy combination of Karl Malone and Magic Johnson in the same body.
Basketball Reference broke him down a few years ago: http://www.basketball-reference.com/blog/?p=4011
Bias was more Bernard King than Lebron. He was an unstoppable scorer.
