Drop Blount for Green or Boldin? WHIR

[BuckAv]

My current "RB bench spot for someone who might be worth points down the line" is currently filled with LaGarrette Blount. He seems to be starting to steal carries and TD chances from Martin. Alex Green and Brandon Bolden are both on waivers. Are either worth dropping Blount for right now? I wouldn't be starting any of them for the immediate future (I have T-Rich and Lynch as my two starters), but they could be in the mix for my flex spot.
