I personally have no interest in trading any of those guys right now.
Offseason? Sure, but not now. In fact, I fully expect Adames and Burnes to be traded this off season. I'd put it at about a 95% chance in both cases barring injury. I have zero interest in an extension with either.
And I'm just fine keeping Yelich. Not worth what it would cost to move him. Also, he's easily our best position player.
