There are many fantasy experts and gurus out there, and you should definitely pay attention to what they have to say (see: an earlier post I made). They will give you insight into why a certain player might be good to play this week, but, at the end of the day, when you are trying to decide between two guys who have similar projections and the experts are split on, just go with your gut.
Trust me, the feeling of leaving a guy on the bench when you wanted to start him is awful when he goes for 30 points. You’ll be mad at yourself, ESPN, and everyone else who told you to start the other guy. Hindsight is 20/20, but you don’t want to kick yourself when you lose by 2 because you started the wrong guy.
At the end of the day, fantasy football is a game, and games are meant to be fun. If everyone said to start Player A, but you wanted to start Player B & didn’t, you’ll wish you did when he has a great game. Plus, you can brag to your friends that you started Player B because of reasons X, Y, and Z.
