Should I be concerned in my fantasy league?

Start L. White for sure since he is the goaline person. He should get a lot of touchdowns at the goalline. Also start Jacobs b/c he should be back next game healthy after going out with an injury. I would keep Jackson b/c he is improving so he should start to do good. I would think about Gore. It's your opinion. If Gore is definetly out then pick up someone from free agents.
