No financially responsible team would be willing to trade for Yelich. I suppose it's possible for a team with an almost unlimited budget to take him, expecting more of the same from him as a floor and dreaming on him returning to MVP-level production. I'd be exploring such trades, but I doubt you could make one.
The alternative would be to trade Yelich and Burnes together for basically nothing (maybe a spare part or very marginal prospect). That doesn't make us better, though we'd be able to afford a couple of serviceable FAs with the cost savings.
I think the most likely successful course would be to expose Yelich to weird religious sects that would cause him to retire, if he joined them. That's the best-case scenario, assuming we don't want to indulge in any foul play. I don't think I'm joking.
