We've been through the whole "Lebron can score if he needs to" in this thread already. There are plenty of stats to back up the fact that he can and does score at historic levels when needed. Although, simply calling him a scorer sells his game short. The Heat offense is designed for him to be a facilitator and have things run through him. Bosh was reliable but not dominant in the Finals. Wade was atrocious, Battier was non existent, Mike Miller was amnestied, Allen was good but played too many minutes, Chalmers was awful. These are the guys who are supposed to help take the scoring load off of Lebron and be active on defense. Neither happened.
Jordan played against simple defenses. The game is so much more cerebral now with the rule changes. If Jordan was getting double or triple teamed it was only after he caught the ball. With good floor spacing, which the triangle had, that makes all the difference in the world. No player could sag off of their man to help until Jordan had the ball. Add in the floor spacing and they would have to cover so much ground to double team that Jordan can already make his one on one move.
Double and triple teams weren't really a thing then either because you couldn't run a weakside zone. If someone came to help on Jordan (or whoever in the 90s) then he would pass the ball out, forcing the help defender away, then get the ball right back. Players "Re-Posted" all the time on the block back then. Get the ball, see the double come, pass it back out to the wing, watch the second defender leave (or get a tech), then get the ball back again with the help defender moving away.
The game allowed for ISO players to do extraordinarily well. Melo would have had better numbers than Jordan if they swapped decades, he is a much more dynamic scorer than Jordan. Because of the evolution of defenses a two trick pony like Jordan wouldn't do well unless he revised his game (he probably would have put in the work to do so) in a big way. His Russell Westbrook-esque three point shooting would have been just as much of a liability for the team as it is for the Thunder now.
Jordan was a great scorer that was fortunate enough to play for the best coach ever, who designed an offense that allowed him to be a volume shooter only and be successful. Jordan scored a couple more points a game on five to six more shots at similar points in their career. Whoop. It helps when you have Rodman on your team, who is the best rebounder the game has ever seen, and it isn't even close, and a stellar defender. Add in Pippen who was able to carry the team to the ECF and two points from making the Finals without Jordan and you have a pretty good team. This notion that Jordan did everything on the floor isn't reality. He scored. He did it in ways that wouldn't be effective today. He did it with efficiency levels closer to Allen Iverson than Lebron James.
Jordan was great in his era. Compare him to Kobe if you want to see what his style of player would do in the modern game. Or Melo would be apt. Or even Durant, though Durant is growing out of the pure scorer mentality. The only comparison you can make between Jordan and Lebron is that they were both head and shoulders better than their competition in their prime.
