I wouldn't do it.
I'd try to get a better, cheaper keeper. Even if that means getting back just one guy.
I am negotiating a Kamara for Thomas trade now. I can't keep Kamara beyond this year and I have L. Murray so Kamara can stay injured as far as I am concerned. Just like last year when Dalvin Cook was hurt and Murray cleaned up. Just need to iron out the throw-in players.
Problem is that the better, cheaper keepers all have value to their current teams in the playoff races. I want to target guys that have limited or no rest-of-season value but do have keeper value. Kerryon Johnson is ideal, or anyone else who suffers a season-ending injury. I just wish he was a better player.
Adams is on a short-term injury, but that has reduced his value some.
There aren't a lot of better, cheaper keepers any longer in our league. Limited unknown guys busting onto the scene recently. Kamara is one, he's $30 next year. But he's on a team going nowhere, so don't see much interest in his owner dealing him. Same goes for Chubb, he'll be $25, but again on a bad team who has no incentive to trade. James Conner is $21 next year but I'd rather have Thomas.
