I am 41 years old - so I will say emphatically that I'm an "old school" / "classic hoops" person. I grew up watching the NBA, and have clear recollections of the game from when I was around 10 years old, which would have been 1982.
I personally believe the "golden age" of the NBA was from 1984 to around 1996. After that time frame, the game began to change, and in my opinion, it was a negative direction. A few things happened:
1) Too much expansion too soon. There were too many teams that came into existence too quickly. it watered down the talent pool.
2) The removal of the 3-year mandatory stay for college basketball players before entering the draft. What happened is that forced teams, REALLY BAD TEAMS, to start drafting players players based upon their "5-year potential". So instead of drafting a player who could help you RIGHT NOW (as a bad team needs), they started taking longer-term projects with early picks. When those players didn't pan out, because they were not prepared for the NBA game, the trickle-down effect was a negative one.
3) Tinkering with the rules of the game. Most notably, the 3-point shot. For a season it was moved in. BAD MOVE. It created a new game where mediocre players were setting records of attempts because of the newer/shorter distance.
4) Way too much emphasis on defense / not enough emphasis on offense. I suppose you could blame this on Pat Riley - and that is odd. When Slick Riley was leading the Lakers, it was "ShowTime" basketball - fast paced and fun to watch. Then all of a sudden the Knicks and Heat are playing basketball like it's a wrestling match. Offense be damned... It started to destroy the game...
5) No more fast-break offense. The 80's saw high scoring games - fun to watch. Guys would run. Passing was excellent. Then the pace slowed down, and guys just stopped running.
I suppose I could ramble even more, but suffice to say, the game, in my opinion, has had a bit of a resurgence THIS season because of the faster pace of play. It's NBA basketball - I WANT to see games that have 130-125 scores. That's old-school basketball. There is still defense, but it's not a boring, suffocating type.
With all that said, I play NBA 2K11 - EXCLUSIVELY. I gave my copy of 2K14 to my kids. I'll never purchase another NBA game ever again for 2 reasons: I recognize I LOVE the old NBA. And I'm an "old" guy, so it makes sense. I'm a classic gamer, and I don't even play games of current teams anymore. Funny, but I create MLB 2K12 rosters - in the last two weeks I work on the roster file, but I NEVER play any games.
Second reason: I'm done purchasing gaming systems. I'm not forking over the money for an XboxOne or a PS4 - not my thing anymore. So NBA 2K11 is IT for me...
**Side note: I put an update for the sliders on Page 1 - Post 1 here in this thread. This game is REALLY coming TO LIFE for me. I played a game last night in which I had 14 offensive rebounds and the cpu had 11. So all the tinkering I've done I've found some things that I'm seeing now that create new stuff. I even saw a new animation last night that I had never seen in playing this game.
**Side note 2: In the "classic rosters / hardwood rosters" thread I've been putting some "game stories" there from the games I'm playing using my old-school NBA 2K11 rosters. I put a write-up together for random games I play from random seasons. This game will never get old for me - I will have counless games to play!! So I'm sharing those stories for anyone interested there.
