Manny is trade bait for 2018 with his contract concluding after the 2018 season.

So long as Manny and his agent want to go to Free Agency, the O's will not get anywhere near fair value in a trade, as they won't sign a long term contract with a new team any more than they would with the O's. A trade deadline panic deal with another team (the one that is in a panic) will bring a better deal than anything now.

If Manny is at best a 1 year rental for other teams, the O's might as well use him for the one year THEY have left.
