Think my NFL Fantasy team will stay strong?

Julius Jones is a basically a backup. I watch Seattle every week. I would start Chris Johnson, he has played well. Also pick up a better WR than Hackett, I'm sure their is someone out there. I just picked up Carlson for my fantasy team. He has been thrown to alot because they so many injuries at WR. Senecca Wallace who is there backup Qb is now playing WR, got hurt during warm ups and another WR got hurt on his first catch. The Seahawks have their preseason practice squad playing.
