Those are tough decisions EM, but I would highly recommend starting both Jackson & Mason. I don't think you could go wrong with either, as they both look like 2nd or 3rd tier guys for you, but as far as scoring more pts, those 2 are best. Lynch faces a tougher run "D" on grass away, while Jax plays at home, on art turf in a dome. Plus he catches more passes (pprec scoring?). Mason is just the safer bet, as Breaston will have up & down gms, as you surely know. If you want to try and hit the homerun, go with Breaston cuz he could break out against a so-so MIN pass "D". But if you want a safe, no frills 8-12 pts, go with Mason. This also depends if you're in a pprec league. Otherwise, if it's TD heavy, I'd go with Breaston. But Mason should get a good amt of rec's against a very stingy PIT "D", cuz Flacco will have to pass quickly, and Mason excels at catching the short stuff. GL.
