The waiver wire is where fantasy seasons are won or lost. The draft is a bit hit-or-miss, and chances are you are going to whiff on a handful of picks that won't be on your team long after Week 1.
However, everyone has the chance to play catch-up on the waiver wire, and if you play your cards right, you could find yourself with players like New Orleans Saints running back Alvin Kamara, who wasn't a hot name during draft season but is now leading fantasy teams everywhere to monster seasons. You can still find key contributors this late in the year, however.
