Would you trade away Roddy White to get Plaxico and Reggie Bush.

Im 6-4 in a 12 team league and have a comfortable ride to make tthe playoffs but feel i need improvement

qb Stafford/Roethlisberger
rb Forte/Benson/D.Thomas/ Jackie Battle (sucks i lost jamaal charles for the year
wr- Roddy White/Bmarsh/N.Washington/Mike Thomas (sucks i lost Kenny Britt for the year
te-Jimmy Graham/ D.Clark

I think its a big risk to give away R. White due to his potential, but I am desperate to get a solid rb. If i get Bush i will have both fins rbs, which will give me a safety net if one gets benched or hurt. Do i pull the trigger?
