I picked Romo, Jennings, and Charles. Romo's a proven QB that can put up huge numbers and now has another weapon in Dez Bryant. Jennings will go back to his form from 2 years ago and prove that last year was a fluke with Aaron Rodgers in his prime. And as for Jamal Charles, he's a very promising back with tremendous upside. Note the 5.7 ypc he had last year.
I went Romo, Charles, Jennings because in a 2QB Quaterbacks become very very very important. Getting Romo is much more valuable than Andre Johnson for example since you can snag Jennings who wont do THAT much worse in the third and you have a stud RB in Charles
I voted Romo, Calvin, Mathews. In a 2 qb league, i think you have to have a top 10 qb. CJ has one of the greatest wr skill sets in the league, and he and Stafford should be more in sync this year. In Mathews you have a back who is NOT sharing carries and plays for a high scoring offense. As for your other q's, I have CJ ranked just one spot ahead of Austin, and Mathews 3 spots higher than Charles, although that might go up a bit as reports continue to have Charles losing carries to Jones. Good luck and please help w/ mine in sig!
