I see Columbus as the cautionary tale from the opposite perspective. That's a team that kept expending futures for years in order to try to stay competitive, and it produced a team with no present or future.
They seem to have changed their course only recently with the firing of Jarmo and embracing a rebuild.
They're kind of both things. They were awful at the start. In 9 years they only got like 2 top shelf players from their top 10 draft picks (Nash and Voracek). After that it's like they got antsy and would draft high for a couple of years before deciding to push their chips in and accelerate the rebuild only to have it fail because they made dumb moves that didn't pay off, but also because they have largely sucked at drafting and can't build that strong backbone from within the organization that is necessary.
Given that basebaseball drafts are
obscene crapshoots and the spectacular bust rate of prospects, I'm wary of expecting a teardown to be the "obvious" path forward. Sure we could be Baltimore, but we could also be the White Sox. Or the Marlins. Or the Rockies. Or the Tigers. This team needs fixing, but burning things to the ground is premature.
