I had this discussion with my brother the other day, he's a big Lee fan.
I think it order to get this done we'd have to offer something substantial. Here's something he came up with that most fans would probably look at and hate at first, but would make a lot of sense...
NY Trades
David Lee
Stephon Marbury
Boston Trades
Ray Allan
Scalabrine
Why this works...
NY is debating on cutting marbury if they can't dump him. He has 1 year at 21 mill left, where as Allan has 2 years and is likely going to decline over that time (I think substantially). It would give us cap relief a year earlier, and also give us a great young talent in Lee to help while PP and KG are here and also in the future.
Allan would be an upgrade and a bigger asset in D'Antoni's system since he's a great pure shooter. He gives NY star power and will attract a big fan base. Scal is filler, I didn't take the time to trade check this, but I know Allan only makes about 17 mill, so we'd have to add someone. Ditching Scal would be a blessing in this as well.
I think most people would hate this trade. But if you read PP's comments on Marbury he really seems to be hinting that he ought to be a Celtic. I hate Marbury myself, but I could see him toning his game down if he was on a team where he had a chance at a ring and was playing with other vets.
I think it'd be a good move.
