Who should fill in for Pendles?

[Chelskiman]

I only have 5 trades and I'd rather not waste one by trading Pendles out just yet, so I need one of SPP or Witherden to step up this week.  SPP is coming off a great 112, but Witherden has been super consistent, so which one do I field?

Would go Witherden - Lions playing the Blues so could keep up 90+

Carlton haven't been easy to score against but I wouldn't be fielding SPP over Witherden. He has  been hit and miss for a lot of the year. I can't see them beating the Dees in Melbourne.

Who would you field out of Greenwood and Witherden?
