Even though it's PPR, I still believe that RBs are very important. You locked those up well.
I have D. Bowe as #8 receiver for PPR, so you're good there. Steve Johnson ranks as a weak WR2, but you got a beast in Finley.
I _HATE_ the Giants defense this year. They've been decimated by injury and are going to be bottom of the pack.
So about the only advice I have is keep your eye on the waiver wire for those breakout wide receivers. They tend to show up every year. See if you can get a stronger WR2, but Johnson is still pretty good. For defense, play the matchups and a decent rule of thumb this year is to take whoever is playing against the Bills
I think you're definitely playoff bound. For a 12 man league, your team is awesome. Good luck
