Top 9 are relatively stable since the offseason. There's a pretty big dropoff from #9 (Cruz) to #10 (Gordon).
The 10s contain a lot of youngish guys with a legitimate shot to put up some top 10 seasons, who are also fairly safe bets to string together a few top 25 seasons. Gordon, Jeffery, and Hilton have put a bit of separation on the other WRs in their first 2 seasons, by putting up performances that are really good without being graded on a curve (not merely good for a rookie). The bottom of this tier contains elite older receivers, who are destined to slide down the rankings as the clock ticks away. Jordy Nelson would belong in the top 10 if he was guaranteed to re-sign with Aaron Rodgers, and he'd belong with the Andre Johnson & Wes Welker group if he was guaranteed to leave town.
Next tier (the 20s) is mostly top prospects who haven't emerged yet (at least not as anything more than a WR3), mixed in with some guys who are likely to top at as WR2s (Torrey Smith, Shorts), carry extra risk (Nicks, Blackmon), or are old (Colston).
Tier 6 (the 30s) mixes young guys with less pedigree or upside, and solid veterans with more warts.
