Wow someone sounds resentful. You truly sound like an old man sitting on a porch yelling at kids to get off your lawn. Mostly because you're missing the forest for the trees.
What the heck do the 3 point line and "obsession with dunks" have to do with bad basketball? Dunks are 2 points, and generally the most efficient way to score possible. Athletes skilled enough to dunk who attempt to dunk probably score at a higher percentage than any other play (think how many layups are missed below the rim). 3 point shots are game changing, and for those skilled at them increase point per shot percentages. A 40% 3 shooter is akin to a 60% 2 point shooter, which is awesome and takes less shots (and possessions) to reach same points. Coaches who don't have the insight or balls to regulate who gets to shoot 3s are the failures.
Don't blame 3's or dunks. Blame the generation parenting and coaching the current generation of players, for not having the balls and courage to break kids down once in awhile to send a message, and for letting politically correct rules govern what truly is best for teams and competition. Basically blame yourselves, stop blaming others. But just as you and I pass blame about why this or that sucks, they'll pass the blame to someone else to. Nothing changes, they learned it from us.
