Hard for me to see the Knicks/Nets ever becoming more than just a regional thing that will, of course, be hyped like it's something that it isn't by the news media. The Knocks have a suprdemely talentd offensive player, Carmelo, who reminds me of Charles Barkley a lot; meaning, an offensive machine but a loser nonethless.
Nets have a better chance, I think. Their pieces do appear to at least fit, unlike the mish mash that is the Knick's roster.
The problem though is that great rivalries are built over time and, and as far as basketball is concened, these two haven't had enough of it.
