RB2 Start: Melvin Gordon, D'Andre Swift, or Tevin Coleman

Full PPR - With Phillip Lindsay looking likely to play tomorrow and Tevin Coleman now activated my confident MGIII start is now diminishing. I also have Swift on the bench, but I worry that the Colts matchup won’t do him any favors. Someone help! Who gets the start and why? I wanna start Tevin but never know what the 49ers are going to do…
