2-0 team looking to improve

[ploki]

My team is 2-0. They're very good. Is it worth unloading a stud RB to pick up WR help?

(2-0) 12 Team Non-PPR (QB Pass TD=4)
QB: RG3
RB: McCoy/Murray/MJD/Spiller/Ingram
WR: Austin/Thomas/Bowe/Smith
TE: Davis/Pitta
K: Kaeding
D: Bills

Any advice would be great. WHIR
