Week 15 is upon us, which means that nearly every fantasy football league is officially in playoff mode. For most of us, the fantasy playoffs began last week. If you're reading this article, I assume your fantasy championship hopes are still alive. Congratulations!

In most fantasy seasons, the players on the waiver wire are largely irrelevant by the time Week 15 rolls around. Sure, some owners got sick of waiting on high-upside handcuff options, such as DeAngelo Williams or Alfred Morris, and present opportunities for savvy owners to bolster their benches.

But, for the most part, Week 15 isn't a time when you can find plug-and-play starters off the waiver wire.

Nothing could be further from the truth this time around, as Week 15 has presented us with several exciting waiver wire additions who could change the landscape of the fantasy playoffs.
