It would have to be a young top4 offensive RD with the abliity to QB a powerplay, locked in long term or having plenty of years of control left.
Who fit's that mould?
Oh, I don't think he gets traded. His name has been out there for too long, so clearly his value wasn't high enough to get what you're asking for. I'm just saying how this "Chia will never trade RNH" stuff isn't entirely true. He tried to trade him, even after trading Hall, so who knows now. Has the ship sailed? Most likely yes, especially with Yak gone, as Snipes mentioned. But I don't believe you can completely close the door on a player who the GM was so keen on moving previously. You never know.
