I'm coming around on Tyreek Hill and Willie Snead. Matt Harmon recently released his Reception Perception data on 50 NFL WRs (behind a
paywall, unfortunately), and they were among the best at getting open reliably. They also both ran a relatively balanced route tree, and were successful at getting open on a wide range of routes and regardless of man/zone/press coverage. They did both run a lot of routes out of the slot, typically off the line of scrimmage, but that isn't a huge negative these days. And the fact that their teams let Cooks and Maclin go is a positive both for getting them more opportunities this year, and as a sign of the confidence that their teams have in them.
I am at least going to be moving each of them up a tier from where I've had them
ranked.
Another interesting stat from Harmon's data - here are the 6 WRs who were double covered on at least 10% of their charted routes: Mike Evans, Dez Bryant, AJ Green, Brandon Marshall, Julio Jones, Odell Beckham, and Antonio Brown. Basically a who's-who of the best traditional #1 WRs.
There are also some interesting names among the WRs who were double covered on less than 5% of their charted routes, including Terrelle Pryor, Jeremy Maclin, Jordy Nelson, Allen Robinson, Kelvin Benjamin, and Sammy Watkins. Possibly a sign that defensive coordinators weren't that worried about them?
Though it's worth noting that Harmon only charted a handful of games for each player (I think 6 games) so these numbers might be influenced by which games Harmon chose to chart (e.g., Pryor might have drawn more double coverage later in the season, or there might have been some non-charted games where the defensive coordinator chose to scheme more aggressively and send more double teams at this receiver).
Looking at Harmon's data on college receivers from the past two draft classes, there are 3 WRs who were double covered on at least 10% of their charted routes: John Ross (2016 season), Taywan Taylor (2016 season), and Corey Davis (2016 season). Coming in under the 5% mark, among receivers drafted in the first 2 rounds: Michael Thomas (2015 season), Laquon Treadwell (2015 season), Will Fuller (2015 season), Tyler Boyd (2015 season), and Corey Coleman (2015 season).
