Dareus or Ansah

After being burned by Ziggy for 2 weeks I took a winger on Dareus who appears to be on the rise while Mario Williams declines.

The Detroit Oline is a mess. You have Ziggy ranked higher and I can grab him off waivers if I dump Dareus.

Thoughts?

I like both this week. I'm just banking on Ansah to break out this week against the Bills who are giving up the most points to defensive ends so far this season.
