Malcolm Jenkins ... Drop or Hold???

I have Jenkins as my CB in my 16 team IDP league that is a big play league scoring 2 points for a PD, 5 points for sacks, FF, FR and 6 points for INT while giving 1 point for tackles/assisted tackles.  I thought Jenkins would be getting plenty of opportunity to make some plays but thus far he has only made 5 tackles with a PD a game.  ON that note I am wondering if I should wait a few more weeks before dropping him for the likes of ...

Marcus Trufant (SEA)
Jabari Greer (NO)
AJ Jefferson (ARI)
Leodis McKelvin (BUF)
Kyle Arrington (NE)
Aaron Ross (NYG)

I would hold him for the time being since there aren't a lot of great WW options available.
