In Part I of this series, I discussed the history of trade deadlines and set forth a primer on the new rules concerning the trade deadline that is now firm for the first time. In Part II, I outlined the types of waivers that have been eliminated and gave some examples of Cardinal players that were affected by the old rules. You can find Part I here, and Part II here. In this final installment, I will tell you everything you need to know about the only types of waivers remaining: unconditional release waivers and outright assignment waivers.
