Week 16 dilemma: Maroney or Stecker

[Chi Dynasty12]

My team has 2 RB spots and its the game to get into the championship this week. My 1st rb spot is secured by adrian peterson, but for the second spot I have to choose between Aaron Stecker or Lawrence Maroney.

Stecker (vs. Eagles) has been huge lately, but theres a chance Reggie Bush might come back from injury to play this week taking away carries.

Maroney on the other hand is playing the Dolphins, so he could have a huge game as its the undefeated team vs the worst team.

any help?
