Coming in late here, but here's my take:
At some point, you gotta trade some of these first basemen instead of continuing to play them out of position. I like Burger, but he's a low-OBP designated hitter on a team that doesn't need that. It's a shame it took this long for these morons to start trading depth for needs, but here we are.
I hope the "player development staff" has identified something specific with Eder, because he's had a really rough year in terms of his stuff and projection. But if they do think they can fix him, it's a really solid return for a one-dimensional player, and I expect the reason they were able to get this much was because of Burger's five year of control.
