The fact that it's PPR is going to save your skin.
Without looking at the other teams in your league, I'm going to say you can make the playoffs, but you'll have a much better chance if you scour the waver wire after week 1 and 2 for a solid WR.
Charles, Sproles, and Bush could all end top 12, I think, so I think you did very well there. Woodhead has been a very good PPR value in most leagues, but that's not a lot of depth. Even when Murray gets hurt, Randle will probably be in a time share, so you're pretty thin there. However, if there's no major injuries to any of those three, you really should be fine there.
WR is a little more sketchy. Marshall should be good in PPR (people overlook this a lot, but in my league Marshall wound up less than half a PPG behind Calvin Johnson) but you don't really have a WR2. I love John Gordon, but I'd be very uncomfortable with him and Britt trading off as my second WR. He and Britt are nice sleeprs, but I'd really try to trade Romo for a second WR and a much cheaper backup QB.
I don't know what you paid for RG3, and if you have him, you need an insurance policy. But springing on two top-8 picks is sort of expensive probably. Unless you got a really good value on one that is. I'd see if you can trade Romo for like maybe DeSean Jackson and Andy Dalton or something like that.
I'm not sure I really buy Brandon Myers, but TE is deep and you can just find a new one worst case scenario. I'd look into Zach Sudfeld perhaps maybe? He's on a ton of waiver wires.
Cincinnati is a good defense. In auction, I don't like spending more than a dollar on any defense, so you probably did it right.
Kickers are kickers.
All in all, I think you did alright. B for stud RBs but thin WR, and A- or so if you can convert Romo into a serviceable backup and a true WR2.
