PT Cruiser or Sims-Walker in the flex PPR WHIR

[dunbar2007]

PT Cruiser is who I'm rolling with currently as Sims-Walker's pathetic last week showing vs. a poor pass defense cost me a victory (I had PThomas on the bench). However, I'm torn!

PPR league
PT vs Carolina? Weak run defense, but splits carries.

or

Sims-walker vs KCC? Terrible pass defense, but last week was vs. a terrible pass defense and did nothing (cost me the game)


Who and why? Will definitely help in return!!!!
