The Qualifying Offer system isn't broken, but it's due for some maintenance. Let's explore some ideas.
Earlier this month, Russell Carleton of Baseball Prospectus argued that the dollar amount for MLB's Qualifying Offer process should be adjusted north of its current figure of $15.8 million. There's quite a bit of math in that link, but Carleton makes several compelling points with his numbers.
All of this is a window into a subject that needs further discussion: The Qualifying Offer in general. My personal feelings on the system are that it's a good idea with a good foundation that needs some tweaks, so I'll offer a few ideas in this piece (feel free to add your own in the comments).
