Now that I'm thinking about this, I dont see how it could ever be as competitive as the NBA.
If the NBA rules somehow changed to favor streetball...how many times can you imagine saying "man why didnt he just put it in instead of all that other fancy stuff"
The fanbase would be more unified instead of fans rooting for teams, because theres no way a street game could match the competitiveness of an nba game if the mentality is "let me look good THEN put it in"
I'm a "score the easiest way possible" type fan. Streetball is a "if it doesnt look good, it dont count"
Even if they made traveling legal, they would have to put some limitations on it, or double dribble. There will always be the player who will use the rules to the limit and score the easiest way possible, when the street players just want the travel legal so they can do their moves. the NBA will never get rid of all the fundamental players unless they COMPLETELY change the rules. We're talking like certain moves get points, and they start doing style points and have judges or something.
The NBA will never resort to that, so the streetball idea would have to be formed on its own and have some money behind it. Players wouldnt make nearly as much money because its not a "bring me a title and well pay this" type situation.
HOWEVER, since streetball already has become very popular in the states, the foreign influence on the league will increase drastically over the next 10 years. I wonder how streetball will influence the foreign game when it starts getting popular there??
