I get AB.
Here is my roster (0-2)
Personally, I wouldn’t strictly because of your roster. Your starting RBs are good but they’re both people with injury volatility. If you get rid of Carson and Johnson goes down or Gurleys knee acts up, you’re going to be up a creek.
What I would personally do is try and package Gurley with another reciever for a WR1 and then have Carson as your RB2.
That way you get rid of the highest injury risk player on your team, still have an above average RB2, and solve your WR dilemma.
