Balmer for Canty at DT?

Balmer is listed as a DT/DE in my league

Also, I have Whitner and Attogwe but can pick up Greene as a FA. Should I swap one of these guys? Love Greene this week but hat to lose Whitner or Attogwe down the stretch.

I'd stay put on all ends. Balmer had a big game because of the Giants dominating them for 60 minutes. He probably has as much value as Canty.
