AJ Klein? (Week 2)

I couldn't help but notice the lack of love for AJ Klein (Kuechly's replacement) in the Week 2 rankings. When Luuuuuke sits he seems to perform extremely well for a waiver wire pickup. I snagged him to spite the guy who had Kuechly, but now I'm considering actually plugging him in my Flex spot over Jamie Collins, who seemed to be dropping back a lot last week. Thoughts?

I would stick with Collins, Pitt is 3-4 WRs passing... Bills are run, run, run, lets.. pass.. no one more run

Good point, I'm bad at matches. Thanks
