The variability in some versions of phantom drafts has a fair bit to do with the evenness of this draft across a wide range of players. It'd also be down to some of the late info they'd be getting from club recruiters, rather than a shift in how they rate the player per se.
The primary reason we shifted from 3 to 7 was to secure McCarthy, a KPP, while this is a draft full of midfielders at the pointy end. I not sure they'd have one definitive player in mind for that pick, but rather they'd think the spread of talent would assure them that, quality wise, there'd be not much between what's available at 3 vs what's available at 7.
