What should I do with my fantasy team?

Felix Jones is a great pick up. Looking at your team I think you should drop John Carlson TE only because TEs are a dime a dozon outside of the top 3. By the time Miller has his bye week you will more than likely have an injury or someone will be doing horrible enough to drop. If Vincent Jackson is available I would pick him up also. The other route you can go is to propose a trade. You will have to give someone up but at the same time gaining more value at a different position. I hope this helps, good luck.
