They've been narrowed once already Keith. Make 'em like Arena League goalposts. (Not just yet)
That's my one complaint about the NBA- they've never raised the baskets. Fans love those power dunks. It's just gotten too easy for the pros. Mutumbo could about dunk not even jumping. We used to play in a grade school gym where you could crank the baskets down to 8'. It's no challenge dribbling till you fake your defender out for an easy slam.
The reason they aren't raising the basket, is both entertainment and records wise. If you don't want to see dunks and are only concerned with solid fundamentals, go watch the WNBA. I heard tickets are real cheap. As far as records go, you have decades of records which would basically be nullified due to changing that rule, much like changing the scoring in the NFL, switching to metal bats in baseball, or removing the goalie in hockey or soccer.
Wilt scored 100? Nope that doesn't mean shit anymore because the hoop was only 10 foot. Peyton threw 55 TDs? Who cares, Andy Douche Bag only had to throw 5 TD'S to equal Peyton's scoring output.
If y'all dumb dumbs want to change the scoring or any other nonsense go right ahead. I'm going to spend my time watching Westbrook try to tear the fucking rim off the backboard 15 times a night while working on making Oscar Roberson's 61-62 season seem like child's play.
