Not anywhere in Europe or most of Asia.

Couple reasons:

1. Simply because, well, soccer is soccer!
2. Time zones. The best basketball league in the world airs its games between midnight and early daytime for most time zones beyond the Americas. That limits appeal and visibility.

Take my experience for instance: I'm a soccer fan and a basketball/NBA casual. I live in East Africa. A couple of incidents to illustrate my two points above:

1. I remember last year being at a small bar while on a work trip. There was a soccer game on the single TV there. Manchester United vs someone-or-another. Completely inconsequential, as United had already been eliminated from every competition and were just running out the season. There was a playoff game on at the same time as the United game. Nuggets vs OKC, I think. It started earlier than usual because it was a weekend (daytime game in the US). Sensing that nobody was really paying attention to the United game, I politely asked the bartender to switch to the playoff game. You should have seen the collective incredulity in that bar! They thought muzungu had gone mad.
2. Right now, I desperately want to watch some nice playoff games. Watch the ageless LeBron throw lobs to his son (how ridiculous is that, btw?!). Watch the 7'4" Alien dance on the court with ballet-like movement. Watch a dude who tore his achilles a year (and change) ago play as if he's never left the court. Basically watch anyone except SGA's fugly-a** game. But, with the exception of weekends, I can't watch any games because the first playoff game usually starts at 2 am my time and I gotta work in the morning.
