"Unlikely". That's the word.
Possible translation:
"I've had some conversations with other teams and indicated that we would gladly trade you for the other team's best young player, several 1st round picks, and the other owner's daughter. We're waiting for a call back."
Danny clearly values and respects Ray, and probably there were conversations to gauge his trade value, and nobody was jumping at Danny's price. It's possible that may change at the deadline and some team may go for it, but it's "unlikely".
Further complicating matters, and making a trade less likely, Houston is probably doing the same thing with T-Mac's contract, which I believe is bigger than Ray's, so we aren't the only team that will be bidding at the fire sale...and Danny won't overbid or take any crap he doesn't want. He'd probably do a minor deal instead, and keep Ray on a cheaper 6th man deal next year. Houston will not do that, they're dealing this year, more than likely.
