Here are preliminary rankings for week 15 playoffs, as we await more detailed injury information. I’ve marked an asterisk next to injury concerns that could affect starting status, and bolded guys who are more likely to be available as a free agent.
The number one free agent is David Wilson. I’ve got him ranked ahead of Bradshaw this week given how explosive he is, and how Bradshaw’s injury. This rank (#15 RB) assumes that Bradshaw plays and Wilson gets around half of the touches. If Bradshaw is ruled out, Wilson is the start of the week and becomes a top 10 option. I’ve currently got both in one league where I am in the semis, and pending further info coming out, plan on starting Wilson this week.
At wide receiver, the best free agent option is probably Jason Avant. Maclin is going to be on the injury report, and Avant has been a solid option anyway with DeSean Jackson already out. He projects as a solid WR3 this week.
