Every week, Scout Fantasy's Pickups article highlights some fringe players that deserve more than just a spot on the waiver wire. You may not want to start them right away, although they're in a great position to succeed.
Your league-mates will likely be going after these guys too so be aggressive when addressing your needs.

Tyrell Williams
I hate to talk about Fantasy implications when a player suffers a serious injury, but it's my job to do so. Keenan Allen's season comes to an end once again. The athletic Williams started being drafted in deeper leagues last week, and now this week, he will be a top add in Fantasy circles.
