Although if the sentence you wrote in bold somehow eventuated (highly unlikely as it is!!), it would show the incredible foresight that someone at UD had when they came up with the 2004/05 Lebron Vs Melo Rivals Box set!!
You mean these?
Not really forsight, these kids were rivals before the draft was over a year earlier. The first Nuggets/Cavs game with Melo and Bron was built up bigger than Ali vs. Frazier. Forsight or smart marketing? Not sure if there's sarcasm there or not.
I'm pretty sure the NBA will see a Cavs/Nuggets Finals eventually, both players revitalised near dead franshises and could one day be the closest player vs player rivalry since Magic Johnson and Larry Bird.
But for now if things could just swing our way, that Bron/Melo Finals series will have to wait...
