Roy, thanks for the reply, and TP.
I'm inclined to agree with Brickowski. The cavaliers, if they almost know that Lebron won't be staying, will be somewhat realistic about trading him. You mentioned Allen, Perk, and Rondo. I'm assuming you mean Ray Allen. Even still, I would do that as a Celtic fan, hands down. Rondo would be the only difficult one to replace from that trade, but it'd be manageable.
One thing to consider is that there is an inherent loss for Lebron if he leaves Cleveland/Ohio. It's the loss of leaving "his" state, and the price for deflating all of the local fans who route for him. I'm not saying he wouldn't leave, but there'd have to be some sort of guarantee for his success. I don't think going to NJ would be enough of a guarantee, nor would the Knicks. It'd be exciting for him until the first 10 games of the season.. then reality would set in.
Does anyone have a tangible projection as to his marketability value in the NY area versus other teams? "Unbuntu" would fly in the face of Lebron's market plan.
