your rb's seem a little weaker than your receiver spot. i guess you're playing for the bye week with receivers. decker seems to be hot news these days, but i don't know how much i trust denver. who do you start right now at the flex?
to me this is a coin flip.. I had both these guys and they scored me close to the same amount of point.. but for flex RB's are better. especially when he gets a majority of the workload
This trade would probably benefit you more in immediate weeks than in the long-term. If that's what you want, I'd go for it. Otherwise I'd target a different RB.
I'm not liking Hightower. Helu could be a factor and Shanahan is horrible to fantasy owners. I would look for Daniel Thomas or even try to get Lynch if he's still around from waivers.
