Being interested and having something to offer are two extremely different things.
How so being interested means you're willing to offer something and outside of KG/Pierce Danny is probably dangling everybody or will be soon
Rondo is the only player on the Celtics roster good enough to tempt Sacramento into parting with DeMarcus Cousins.
The Celtics cannot make any other viable trade package.
Sacramento won't get a player of Rondo's caliber for Cousins at this point. I would have been more likely to agree with you last year.
I agree
It's not that it will take a player of Rondo's ability to land Cousins. It wouldn't. Sacramento won't get offers of that level for Cousins.
It's that Boston lacks assets of comparable value to Cousins. That outside of Rondo, they can't make an offer that is worthwhile for the Kings organization.
The Celtics have one excellent asset in Rondo. Then a bunch of old guys (Pierce, Garnett, Terry) coming towards the end of their career. A bunch of role players (Bass, Green, Lee) on long term deals. One good young talent in Bradley (maybe two depending on specific team's view of J.Green) and a pair of solid assets in Sully in Fab Melo.
It's that Boston lacks the assets to make a realistic offer for Cousins with it's non-Rondo assets. The team just doesn't have the talent (or proven talent if you like) to make an acceptable trade offer. That Boston's only way to get Cousins at this point in time would be to make Rondo available.
