What is Antonio Brown worth?

I’m sitting at 7-1 and have been dominant up until last week’s disgrace of a showing. I’m all but in the playoffs, but i’m worried I’m getting complacent and not setting myself up for Weeks 14-16 well enough. Nothing worse than being the best regular season team only to get bounced for an early playoff exit. My roster is as follows:

QB - Alex Smith (N/A)
RB - Leonard Fournette ($23)
RB - Kareem Hunt ($41)
WR - Julio Jones ($85)
WR - Larry Fitzgerald ($11)
WR - Devin Funchess (N/A)
TE - Zach Ertz ($5)

Ameer Abdullah ($7)
DeMarco Murray ($17)
DeAndre Washington (N/A)
Danny Woodhead ($9)
Randall Cobb ($5)
Cooper Kupp ($1)
Jimmy Graham ($7)

Aaron Rodgers ($32)

What would you be willing to give up for Antonio Brown? I feel like he’d put my team over the edge, but I’m not sure it’s possible to get him without giving up Hunt or Fournette.

Any thoughts are much appreciated.
