What is a "forced buyer?"
There's some real revisionist history going on here. Arraez won a SS and was getting MVP votes, Berrios had one down year but has otherwise been the exact guy Toronto thought they were getting for the other 2.5 seasons, plus he absolutely shoved at Target Field during that WC series. Topa and Anthony DeSclafani were part of the Polanco swap, but the Twins are "way ahead," because a prospect in A/AA has had a good half season after crashing out last year? Paddack and Emilio Pagan? Most of what you've listed is far from a slam dunk, if even a W for the Twins. Duran and Ryan are obvious wins. Nobody should really complain about the Gray swap regardless of Petty's future.
This "competitive," team is about to miss the playoffs for the 4th time in 5 seasons. I mean, what are we talking about here. Management is the issue? Who hires management? The organization is chock full of quality hitters but the offense continues to sputter? We're still waiting on the vaunted "pipeline." Someday right?
The Twins have serious issues with talent identification and/or development, so yeah, it makes sense that fans wouldn't want the person most responsible for these issues, to be the one pulling the trigger on moves at a pivotal deadline.
