rate my team 8th pick

Your RB's are stacked Bird, damn, Solid Group u got there of backs..  How many can u plug in at a time ?  2 RB's + a Flex ?? so 3 total

i would say your WR's are ok, Marshall and jackson are solid but after them i think it falls off alot, Crabtree sucks and Rice is coming off shoulder surgery so he's a Big question mark in my opinion but could possibly pan out to be a decent #2.. 

 very good TE in Hernandez who i think will have a Big year..

Personally i would trade one of them RB's for a Good QB, RG3 i dont think should start for a Fantasy team but i could be dead wrong, he's so talented and has the legs to run outta trouble but still a Rookie..  

is Seattle's Wilson on the FA-Waiver List still ?  

see how the 1st 2 wks go and if ur struggling at QB trade Murray or C.Johnson.

I dont see how you sniff the playoffs. Even at maximum efficiency from CJ, BPD and Hernendez you will have to rely on many unknowns. DeSean is a capable of making great plays at any time, but if he is your starter every week, you're going to have many dissapointments, he is also a small less tham durable guy. I love DeMarco and even though I missed him in every draft, I wish nothing but the best for. He has lots of potential and should have the most productive season as a Cowboy since E. Smith. So, if hes clicking on all cylinders then you may have something. Another risk you carry is at QB. RG3 will either struggle or give you solid numbers based on what he does on the ground. Mike Vick has averaged 47 yards per game in his career, and .3 Rushing TD's per game. Thats alot of production and this kid has that kind of potential and is said to be advanced  than Vick was.

I dont mean to discount your team, especially in the preseason, but honestly everything will have to fall into place in order to win a title.
