Three parts to this question:
1. Based on my team (below) would I be crazy to try and trade for AB?
2. Do you think he will be picked up soon?
3. What do you think his trade value is / what would be a fair trade?
Here is my team (PPR):
QB - Winston / Goff
RB - McCaffrey / Chubb / Mack / D. Johnson / Mattison
WR - Woods / Cooks / S Watkins / G Allison / D Thomas / A Miller
TE - Kelce / Burton
D - Chicago / Houston
K - Fairbairn
