I was never a huge fan of the Madrigal pick because I like upside, however, here are some ways that the situation is similar:
Madrigal was the 4th pick in the draft. Vaughn was the 3rd pick.
Madrigal came up, was somewhat disappointing, but then showed flashes of offensive potential, especially in the last month before he was hurt. Vaughn came up, struggled (especially against RH sliders,) then showed flashes of offensive potential before getting hurt/wearing down in the last two months. And like Madrigal, Vaughn is currently injured even if it's not severe.
Madrigal and Vaughn both hit RH, so are somewhat replaceable given the Sox have other RH options. (Perhaps they believe that Burger could be a pretty good 1b/DH option down the road)
This is the exact same front office, and they seem to value the now in extraordinary ways. Just look at all the 30+ players they've added in the last couple of years.
I think this would be a moronic thing to do, but given their track record of trading Semien/Bassitt for Samardzija, Tatis for Shields, and Madrigal/Heuer for Kimbrel, I just don't see how you can 100% rule out them doing something this stupid again.
