Well yeah if you're comparing what we have in February to what we had after the combine/draft last year then sure.
If anything at this point I'd say the top couple tiers are a lot clearer right now for this year than they were at the same point last year. Remember last year at this point it was Fournette/Cook and then a hodgepodge of like 15 guys. McCaffrey didn't jump to the top tier until he blew up the combine, Mixon at this point most people still thought would go undrafted in the NFL draft, and the Corey Davis hype hadn't built up yet and didn't really solidify him into a top tier player until he was drafted in the top 5 of the NFL draft into a situation that most people considered very good.
We already have things narrowed down pretty well this year. After the combine/draft adding more clarity to that, I think the tiers will be very clear.
