By utilizing our play-by-play data, we're able to identify where each wide receiver and cornerback lines up on each play. By tracking matchups between the two positions, including potential shadow situations, we can offer the best projections, rankings and fantasy advice each week this NFL season.
Below are the matchups you can expect to see during this weekend's four divisional playoff games.
To view the primary defenders and the top three wide receivers that each team will see this weekend, be sure to check out our weekly WR vs. CB cheat sheet.
Because of the size of the chart in the PDF, here is a key to help you get the most out of it each week:
Rt = Number of routes run by each player during the 2017 season
LWR/Slot/RWR = Percentage of the player's routes run from left wide receiver, the slot and right wide receiver, respectively
T/R = Percentage of a player's pass routes on which he's targeted
F/R = Fantasy points per pass route
Green suggests an advantage for the offensive player, while red indicates an advantage for the defender
An "S" indicates projected shadow coverage
Darby has been solid this season, but he's been heavily targeted and has given up a ton of yardage. Mills has struggled again this year and no corner has been targeted more often. Expect Jones to be busy against both corners as the Eagles don't shadow. Robinson has been terrific in the slot, which means Sanu (68 percent slot) will have his hands full.
Jeffery works on the perimeter 84 percent of the time and spends a fairly even share between the left and right side. Atlanta doesn't shadow, so expect Alford and, to a slightly lesser extent, Trufant to be on Philadelphia's top receiver often. Atlanta has been lit up by the slot all season, so Agholor gets a boost against Poole.
In a nutshell, the Patriots usually shadow the opposing team's bigger receiver with 6-foot-1 Gilmore and the smaller/shiftier receiver with 5-foot-11 Butler. Assuming that's the plan this week, Gilmore will be on 6-foot-3 Davis, and Butler on 6-foot Matthews. Both Patriots corners have played very well this season, so this is a downgrade for both of Marcus Mariota's top wideouts. New England allowed the most fantasy points to the slot during the regular season, which is good news for Decker against struggling Rowe.
Jackson shadowed Tyreek Hill part-time last week and has also chased the likes of Marquise Goodwin, T.Y. Hilton and Antonio Brown over the past two months. That said, expect Jackson to follow the speedy Cooks on Saturday night. Jackson's play has progressed during the season, but it's not a terribly tough matchup for Cooks. Ryan has been solid this year, but Tennessee has allowed a lot of production to the slot. Smith has moved ahead of Brice McCain on the depth chart and has played well. If Jackson shadows Cooks, Smith will see a lot of Hogan.
The Steelers shadowed only once (vs. DeAndre Hopkins) during the regular season, so don't expect them to suddenly start doing so against a Jaguars team without a clear No. 1 target. Burns and Haden have played well on the perimeter this year, which means Westbrook (89 percent perimeter) and Lee (87 percent) figure to be held in check. Hilton has been one of the game's better slot corners, which also puts a damper on Hurns' outlook. No. 4 receiver Keelan Cole lined up outside on 10 of his 12 routes last week.
When these teams met in Week 5, Jacksonville moved Ramsey and Bouye around and did not use either one to clearly shadow Brown. It's possible Ramsey will travel with Brown this week, but I'd call it unlikely considering that Brown caught eight of 10 targets for 137 yards on 20 routes lined up against Ramsey and two of eight targets for 20 yards on 28 routes against Bouye in the first meeting between these clubs. Brown certainly lit up Jacksonville in Week 5, but this is one of the game's best secondaries, so it's obviously somewhat of a downgrade. Slot man Colvin hasn't surrendered much production this season, but Smith-Schuster is unlikely to see his targets reduced in this one.
Rhodes has shadowed in nearly every game this season, though one of the exceptions happened to be Week 1 against the Saints. Expect a new plan this week, considering both Thomas' dominant play and Rhodes' recent usage. It's an obviously tough matchup for Thomas. Ginn has been red-hot and has a plus matchup against Waynes on the other side.
Lattimore has shadowed often this season but chased Diggs only four times in the first meeting between these teams. I expect New Orleans to try to get its top corner on Diggs and Thielen when they're lined up on the perimeter (as opposed to covering Treadwell or Michael Floyd), but don't expect full-on shadow coverage on any individual receiver. Thielen (52 percent slot) has a good matchup against Williams.
