Cosell Fantasy Film: Christian Kirk - 2019

In this series of articles, our resident tape wizard Greg Cosell will take an in-depth look at some of the more interesting fantasy players for the 2020 NFL season. It’s a peek behind the curtain of the film room, as these are Greg’s raw, unfiltered notes he takes as he watches a player.

With a new offense and a supremely talented rookie QB, Cardinals WR Christian Kirk was a very popular breakout pick in 2019. While he flashed in his second season, nagging injuries robbed him of action for the second straight year — Kirk has missed seven games in two seasons.

Now, he’s the clear #2 to DeAndre Hopkins for the Cardinals, who are hoping to take a big step forward in Year Two for QB Kyler Murray and coach Kliff Kingsbury. If Kirk can stay on the field, what does he bring to the table?

Kirk’s Traits

  • What immediately stood out was Kirk’s natural quickness, both as a route runner and run-after-catch. Kirk is more quick than straight-line fast and explosive.

  • Kirk showed excellent short-area quickness as a route runner. He’s effective in the slot running choice routes, option routes, and pivot routes.

  • Kirk flashed the understanding of how to use his vertical stem to attack the leverage of corners and create separation at the top of his route stem.

  • Kirk is effective in the WR screen game with his plus run-after-catch ability. Given this, he can also be effective on jet sweeps with his burst and speed to the perimeter.

  • When aligned as an X receiver, Kirk had clear limitations with his size. He was not the kind of receiver who was going to make contested 50/50 catches.

  • Overall, Kirk showed excellent quickness as a route runner with the ability to work effectively from the slot. He also showed enough speed on the outside to, at times, get on top of corners.

  • Kirk fits the profile of an NFL slot receiver with his size and overall traits, and that would likely be his predominant position in a more conventional NFL offense.

  • My sense is Kirk has the traits to be a quality WR who is location-versatile within the Cardinals’ offense. As Kingsbury grows as a coach and gains more experience, and Murray theoretically improves, I believe Kirk will become more of a factor in the passing game.

Usage Observations

  • Kirk stats: 68/709/3 (10.4 YPR, 108 targets)
  • Kirk lined up in multiple positions in the Cards’ shotgun spread offense: he aligned in different splits both outside and in the slot, including inside slot to trips in 3x1 sets (a predominant location for Kirk).
  • In 2x2 sets out of 10 personnel, Kirk almost always aligned in the slot – Larry Fitzgerald was the other slot to the opposite side.
  • There were snaps on which Kirk was the boundary X in both 2x1 and 3x1 sets – he was alignment versatile in Kingsbury’s Air Raid offense.
  • Kirk played significant snaps outside, especially as the Cards moved to more 11 personnel groupings later in the season – over the last half of the season, Kirk consistently lined up on the outside.
  • Kirk was also used as a movement receiver with multiple motion concepts, including jet sweep and orbit reverse.
  • One route Kirk ran from the inside slot to trips was the deep sail route. It is the old “Y-Sail” concept that has always been part of the Air Raid offense. He ran this on his 34-yard reception against the Ravens.
  • There were concepts in which the Cards got the ball to Kirk in space to take advantage of his run-after-catch ability. Innovative screen concepts were one way to do this.
  • Kirk ran a lot of quick-game sit routes — these are easy receptions, but for minimal yards with no run-after-catch.
  • Kirk’s 33-yard TD against the Buccaneers came on a straight go route. The Bucs were in Cover 6 with CB Sean Murphy-Bunting in quarters. Murphy-Bunting had his eyes inside and did not react quickly enough to Kirk’s go route – it was more of a poor play by a rookie corner than an example of Kirk’s speed.
  • With Hopkins now in Arizona, and likely the boundary X receiver, in most formations I would expect Kirk to be a movement Z and slot receiver.
