May take a while but maybe sooner. The way the game is being played right now, the scoring title can be over took sooner. We are seeing high scoring games lately and I barely see games with scores under 100. Stars are shooting 3s like it is just a perimeter shot. If this kind of game continues, a prolific scorer with a durable body will be able to do it.
Aside from that, the league is now improving and even the big guys now are shooting beyond the arc with high percentage. So different from what he saw back in the day because the big guys are focused to guard the center and doing the most physical play. And, I almost forgot, this season alone, it's quite unexpected that players are now easily putting 40-50 points in any given game.
Probably but the key is how consistent they will be in the future in order to beat that record to be set by Lebron before he retires. Even if this guys are scoring 40-50 points in any game but they are not that consistent, missing games and injuries it will be hard to break that record.
There are no one in the top 10 of the scoring leaders that are active, the closest is #14 who is Kevin Durant, and then Harden and Westbrook #27 and #28 on that list.
