I would say even Marvin. Unless you're a contender (or even a pretender), sending assets (even small ones) to a team for an expiring UFA is just plain stupid. Hopefully there are some stupid teams out there.
This is Cleveland we're talking about. If I were them, I'd just waive Bynum and consider it a lesson learned, unless they really value Gasol. But then again, I'm not them. They are them and I'm grateful for that.
