Lebron James has gone to six NBA Finals in a row, seven in his career, by the age of 32. And whenever that gets brought up, it's marveled at, but it's often accompanied by an exclamation of how he did this in a decidedly weaker Eastern conference. [There was an earlier reddit post about when the "weak East" narrative had become a thing.](

While we can get into other factors, one thing that I think isn't acknowledged or discussed much is that this is partially an indictment against the draft system itself. As it stands, it makes it easier for the West to stay good, and easier for the East to stay mediocre.
There are three ways this happens.
1) **The cut-off for the playoffs:**
[I'm going to be using the 2013-2014 NBA season as my example here](
http://www.nba.com/standings/2013/team_record_comparison/conferenceNew_Std_Cnf.html). This year is semi-infamous for a 48 win team, led by an unlikely group of overachieving, scrappy players, including the seemingly cursed Goran Dragic, missing the playoffs. The west's 8th seed that year was a 49 wins Dallas team.
Meanwhile, 48 wins would've been enough to give Phoenix 3rd, 4th, or 5th seed in the East that year. The East's 8th seed that year? A 38 win Atlanta team.
But take a second and consider, did the Hawks benefit long-term from that playoff appearance? This sub discusses teams needing to blow it up and tank, or at least proceed with a clear direction for the future, so often, but here, a team that had far less talent is getting kicked out of the lottery and guaranteed a bottom 16 pick, while a talented Phoenix team enters the lottery with a guaranteed top 14 pick. As it stands, if you want to complain about how teams in the West get screwed over and how they would make the playoffs in the East, it only seems fair to complain about how the teams in the West get to keep adding talent to already talented teams. This issue gets worse when you consider the next point:
2) **The deception of the win-loss records**
Go back to that 48 win Suns team, and that 38 win Hawks team. That situation is even stupider than it looks at first, because the Suns are winning against opponents who, on average, or far tougher opponents, and the Hawks are winning against worse teams. So 48 vs 38 isn't really accurate; the disparity in talent is even worse than it first appears.
Take a look at the current standings. The New Yorks Knicks have a record of 31-51, and the Minnesota Timberwolves have a record of 31-51. As it stands, their draft lottery odds are split, and they will likely be within one spot of the other when it comes to drafting by standing.
But if the West is so much better, that means the Timberwolves are only playing 30 games against the weaker conference, and the Knicks 30 games against the stronger conference. If both teams were put into the same conference, the Timberwolves would probably have a better record than the Knicks. Hell, this isn't just because, given the same opponents, the the Wolves are likely to win more than the Knicks, but also because those two teams are now playing each other more.
Look at two playoff teams: the Bulls and the Blazers. Even with the Blazers' struggles early on, does anyone really think they wouldn't have a record better than 0.500 if they were in the East? Yet the same situation comes up.
To an extent, this issue can also be brought up with divisions. The Southbest rips itself into shreds every year, playing each other more than any other teams in the conference. But you don't really hear as much about divisions, especially because they don't impact playoff standings much (anymore, that is. I'm looking at you, Portland)
3) **Travel Fatigue**
This stupid situation gets even worse when you also consider [this map (map of location of NBA franchises and what divisions they are in)](

What's that? You're telling me the western conference covers 3 time zones to the East's 2? That both of the franchises with higher elevation that make playing there harder (Jazz and Nuggets) are in the West? That the Northwest division stretches the definition of "Northwest" to ridiculous lengths? That, going by geographic distance, the western conference teams, especially on the west coast, are going to spending far more time on the plane than teams in the east?
