I'm in a 10 team ppr 6 pt passing tds. 2 flex. I'm loaded at wr but weak at rb. The only "luxury" I have is 2 qbs I drafted pretty high. Brees in the 4th and Stafford in the 10th. WRs are Green, Fitz, Diggs, Garçon, Maclin and Ginn. Rbs are Ajayi, Hunt, Woodhead, Sproles, and Rawls.
I'm thinking about grabbing one more "lottery" back like James Conner but the only conceivable drop to me would be Stafford and then just roll with Brees even in poor matchups like W1 in Minnesota. But then I wasted my 10th Rd pick. What should I do?

Thanks for the advice.
Jim
