Seattle DE Nwosu

Nwosu is a DE in my league but Seattle depth chart shows him as second string SLB.  His stats of late look much stronger than 1st stringer Mafe.  Is Nwosu worth a pick up as a DE?  I haven't seen anything in your articles about him.  Thanks.

His usage has ramped up in the last couple weeks (was 25% and now around 70%). As with all questions like this, whether to pick him up or not depends on your other available options.
