In today's Stat Snapshot from ProFootballFocus, Legedu Naanee comes up 3rd worst in the league, among WRs, in Yards per Route Run - averaging a mere .069 yards per. If you scan the entire article, you'll see that Steve Smith ranks #7 on the list, and that Jeremy Shockey is #6 among TEs. Some of the other names from around the league may surprise you (Jeff King currently at #1 among TEs, perhaps, or Zach Miller, Brent Celek and Antonio Gates as the worst 3 TE, according to that measurement.) As PFF correctly states, this is not a definitive measurement of a player's value, only a "piece of information," but, as they also say, "some players are getting it done, and others aren't."
