Yep, I'm of the same opinion. There has to be a couple trade offers that he has received that are close to being what we need, but why hurry unless its an offer you can't refuse. I know there will be more than one team that gets a little more desperate for help at top line RHD as the season progresses, and the offers won't get worse.
Whether they will get significantly better depends on how many teams join the fray as Nov roles along. If none do, and the offers truly are inadequate, he'll go back to Trouba with one more offer (which surely won't have got better over time) OR he'll decide to make a move on an offer out there on the table.
If the offer is indeed as you stated, I'd be more than happy with that. If its not good enough and Trouba continues to play hardball, I'm sure there will be little hesitation to let this slip until next summer.
