Definitely one of those cases where mocks <> reality. If you have a mock guy (sorry Soulfly) in Cleveland who believes the RG3 story that he can rekindle 2012 and that the OL will be fine without Mack/Schwartz, he's going to pass on Cook. Same with Andy for Denver. Last mock he took Cook, so he's doing something different. Also, hard to work out a trade when the picks go so slow, whereas in the NFL, that is their job so they are watching everything and paying attention when people drop.
I have to think Lynch dropped further than I think he will in reality and Cook as well. QBs will always be at a premium in the real NFL, but in FF mocks not so much. Maybe I am proven wrong, but I'd be shocked if Cook lasts this long. In this mock, he could easily keep dropping.
