My wife and I played basketball for DIII Wartburg back in the day (late '70s). The women had a 30 second shot clock then (and still do). Mens basketball in the Iowa Conference experimented with a 30 second shot clock as well. Rarely did the shot clock come into play in either game.
And I don't agree about the lack of talent. I think the athletic talent is MUCH better today. However, I think today's players rely more on their athletic ability and don't really learn fundamentals. And that lack of fundamentals helps lead to lower scoring. A pick and roll where the picker pivots properly on the correct foot will make him open EVERY time; sadly, it isn't done today. And off-ball screens, the players today simply don't set up their man in order to use the pick properly. Sealing your man on the post is rarely done and when it is done, the passer doesn't understand the angle or the placement of the pass to feed the post. Finishing around the basket with either hand is a lost art. Boxing out? VERY rarely. All these things add up to poorer field goal percentages due to bad shots or contested shots.
I do agree about the scouting. You can get video of any opponent easily today and the coaching/manager staff is larger today so you have more people going over that video to create a defensive plan.
