My preference has always been for quick access to box scores. Been years now, but I used to have box score displays which highlighted the remarkable stats (e.g., 10+ boards, 20+ points, notable steals, etc). Anything that makes stats access slow drives me nuts, and the NBL is pretty good at that! I've always liked ESPN's setup, in comparison, though even then it presents a Gamecast/whatever first rather than boxscore.
My guess with the current NBL site is that they're hamstrung by whoever is providing the boxscore framework (whatever FIBA use?) and that's why they're showing a frame within a frame, and the actual boxscore itself is embedded down page. Realistically though, you can write a parser to scrape boxscores and display them in a better format, even on the fly or periodically in case data updates - if someone hapless like me can do it with regex, any programmer could do it.
