The only trade I would consider is the last one. You clearly need some help at RB and at 1-5, you have to take chances and it's now or never. I would counter and try and get that same trade, with a better WR than Sanders. Getting Bell and CJ2K actually isn't a terrible return, because as I said, you have to take some risks at this point. Bell could end up being a solid RB2 the rest of the way and CJ2K could break out at anytime.
If you are not wanting to take that risk, I would consider plugging Zac Stacy into your lineup, then going out and getting Andre Brown and Shane Vereen off of waivers in the next couple of weeks. This will give you help later rather than now like the trade, but if your team could pull of some wins before then, you might be in ok shape.
The way I look at it, sitting with only 1 win, you are going to have to give up some of your best players to take a risk on some others. If you don't like any of those 3 trades enough, try and look to deal Spiller and or Cruz elsewhere for an RB2 and solid WR.
