I was fully with you until this part! C'mon, Ted, that's the one thing the Marlins HAVE done extremely well in recent years: unlock talented pitchers. Luzardo arrived to them 3 years ago at a career crossroads and they have turned him into a genuine No. 2/No. 3 starter. They even have another guy in their current rotation, Ryan Weathers, who is on a similar trajectory (though Weathers is doubtful to be on the block at this deadline).
Brooks Lee is a logical centerpiece in such a deal, but I think there would need to be a couple substantial additional pieces to outbid other interested teams.
