Ngata or Jones this week?

Jones has outplayed Ngata  for the last 3 weeks.
I havent seen the # of snaps for this week yet (he played 20 or so less snaps than Ngata last week), but what do you think about Jones for next week?

Ngata got 68 snaps
Jones got 43 snaps

How is it that Jones keeps outproducing Ngata?
It's must win time for me this week.  I can sit Ngata or drop him.  What do you think?

Also, since I have you here, I'm facing some difficult matchup choices with good players:

JPP vs ATL or Dunlap vs Eagles this week?

Skrine of the Browns plays not the corner, but the slot corner right?  Big upside week for him if RG3 is out and his backup wants to use the slot for consistent chain moving?
I have Corey Graham who's playing Denver, and am considering picking up Vaughn who plays HOU.
So, Graham, Skrine, Vaughn = pick 2 best.

Moore vs NYG, Rolle vs ATL, and Dawan Landry vs. MIA ==Pick 2 ....or I can even drop one of them and  try to and get Stevie Brown off the WW tonight.

Finally, Riley vs CLE, or DJ Willliams vs BAL?  I was going to drop DJ...but dunno if Riley has that great of a matchup.

Thanks Guru!

I dropped DJ since it appears he'll share his snaps this week.
Also, Stevie Brown got picked up...but I still have Moore, Rolle, Landry (gotta decide on two)

I'd roll with Rolle and Landry.
