I was just thinking out loud when I wrote that, so I have no issue acknowledging that it could be eventually proved false. We're all just speculating here because of the unknown. I didn't have him last year but I have in the past, and when I did, he was not an every week starter for me.
And it all depends on where he's being drafted if we're looking at more consistent week to week starters. If he's being drafted in the 3rd rd as a backend WR1, I do think you can find safer picks; maybe not the upside, but more consistent. If we're talking in the 4/5 rd as a WR2, then I'd be very content with that value.
I tend to play in keeper/dynasty formats so I really don't think about redraft scenarios. I think consistency is more elusive than you think. Check out Julio Jones' game logs. His 12 reception, 300 yard game was sandwiched between a 1 for 16 and 2 for 29. Cooks finished as the 10th WR in our scoring system. Can't sit him.
What will 2017 bring? Don't know. All we can do is speculate. Cooks could wash out in NE - their offense is complicated and demanding. He could also blossom. I never under estimate BB or think I can predict him. I think he is constantly evolving.
