We didn't necessarily just "flush it down the toilet".
Granted, the benefit we got from him this year was negligible & he may quite possibly sign elsewhere. But, if he does...
depending on what we do elsewhere WRT Free Agent signings & losses, we may very well be entitled to compensation if he signs elsewhere. Doubtful it'll be a 3rd round, but if it's a 4th you got a contributor for a fraction of a season which served as a "tryout" for next season (I don't think you should discount this benefit) tghat seems like a worthwhile trade, even if the compensatory pick is delayed a year.
