what I found interesting in looking over those numbers (and thanks for the link, btw!) is that cleveland had the highest half-time advantage but it was only a mere 6.4 points...
it's not so much the 4th quarter numbers that i'm focusing on, which is where i think the confusion is coming into my posts (and my apologies for not clarifying that better)... my point has been to say that teams don't seem to play that hard in the early 1/2 to 3/4ths of the game - and the fact nba champion lakers were only 6.4 points in the black after 3 quarters (on average), well, personally i found that a bit surprising.
i wish that site went back further in time because i'd be curious to see how those numbers compared to 80's when it seemed that the better teams won by a larger margin (but i could be wrong). and then the league wasn't watered down by expansion or players entering the nba with less than 3 years of college basketball under their belt.
i'm not wanting to make a stink about this, but i just don't believe the quality of basketball is all that great anymore. people don't want the nba to play like college basketball (ie. motion offense and a lack of a post game), and if the game turns into 5 guys who all want to play on the perimeter then fans will sour on it. afterall, how many complaints do we see here about the celtics becoming a perimeter team...people couldn't stand rick pitino's approach to the nba (thinking he could press full-court for 82 games) and even jim o'brien's chuck it from down-town offense...
people don't want the nba to become a league of gimmicks, and if it does the older generation will walk away from the game. the younger generation has a different attitude (largely) in that it's not about the competition, but rather about entertainment and participation. there are so many other options out there for entertainment, and the rise of ticket prices, that if they screw up this next CBA it might spell some trouble for professional basketball...
