I have to admit I skipped several chapters of this thread, so if this point has already been made, I apologize.
NBA teams are much better than college teams at making an extra pass with time ticking off the shot clock and finding an open look.
NBA teams, for example, can do a lot more to set up a shot when inbounding the ball with 2 or 3 seconds on the clock than most college teams would ever dream of attempting.
That said, I watched the finals last night with an eye toward counting how many front court passes were made per possession by the two best NBA teams out there this year.
There were rare possessions that made it to 5 passes. Some didn't involve any: The guy who crossed mid-court with the ball kept it for the entire possession until shooting. Most possessions involved 1 or 2 front-court passes.
To me, that's just not an interesting form of basketball. I like watching college teams who are good at it working the ball for an open shot. I fear that cutting the shot clock to 30 seconds will do more harm to the game than helping scoring.
