They get twelve years of control of two major league ready relievers. Fulmer obviously has not been good the last couple years, but it would be far from surprising to see him be a very good major league reliever. It is in there somewhere. Bummer is meh, I agree, but he's cheap and he's serviceable. I agree now is the right time to trade Rivera from the Sox perspective, but he will all of 2019 as a 24 year old...coming off an .850 OPS season. He is a decent guy to take a chance on for LAD. Definitely one of the Sox top 25 or so prospects.
