🕳3. Filling a void on the defensive line

The Indianapolis Colt will be without center Ryan Kelly for at least the next four games after placing the former Alabama All-American on injured reserve on Tuesday.

The Colts announced Kelly had gone on IR without disclosing his injury.

Kelly appeared on last week’s injury report with calf and knee ailments. He did not practice on Wednesday but returned on Thursday and Friday and played every offensive snap in Indianapolis’ 21-13 loss to the Minnesota Vikings on Sunday night.

Injured-reserve rules require players to be sidelined for at least four games. The Colts have eight games remaining on their regular-season schedule. Indianapolis’ next four games are against the Buffalo Bills on Sunday, New York Jets on Nov. 17, Detroit Lions on Nov. 24 and New England Patriots on Dec. 1.

Kelly already has missed two games this season on Sept. 29 and Oct. 6 because of a neck injury. Tanor Bortolini, a 2024 fourth-round draft choice from Wisconsin, filled in for Kelly when he was out.

The 18th selection of the 2016 NFL Draft, Kelly has spent his entire NFL career with Indianapolis as the Colts’ starting center. He earned Pro Bowl recognition in the 2019, 2020, 2021 and 2023 seasons.

The Indianapolis Colts’ fanbase was in near unanimous agreement that Defensive Coordinator Gus Bradley had to be fired at the end of the season following the team’s 37-34 loss to the Jacksonville Jaguars in week five. Amid the Colts’ own offensive turmoil in the month since that game, Bradley has quietly figured out a winning formula with his defense since that disaster.

The Colts’ defense has been on a steady roll these past four games, ranking as the 8th-best defense in terms of EPA/play, the 9th-best defense in drop back EPA, and the 10th-best defense in rush EPA. While it could be easy to attribute this success to games against Will Levis and Tyler Huntley, the Colts also managed to hold the Minnesota Vikings and the Houston Texans below their usual offensive averages in EPA/play (and rank 6th in EPA/play in general as a defense the past two weeks).

There are a lot of contributing factors to the Colts’ defensive rebound over the past month. It helps to have back-to-back get-right games against vulnerable offenses like the Tennessee Titans and the Miami Dolphins to kick off the stretch, and the momentum built up from those games has carried over into big contests against playoff-bound opponents.

Another factor that has contributed to the Colts’ success has been the return of DeForest Buckner to the lineup. Buckner has been back in the lineup for the Colts’ last two outings, logging four hurries, three quarterback hits, and two sacks since returning to the field. His elite presence on the interior has paved the way for the rest of the Colts’ defensive line returning to their early season expectations.

The final massive factor in this defensive growth in none other than Gus Bradley himself. Once the old dog that would never learn a new trick, Bradley has changed this defense up a good bit in recent weeks. A man known for his lack of aggression and for sitting back in cover three all day long has shifted to more of a blitz-heavy cover two defense in recent weeks.

This shift for the Colts’ defense is eerily similar to the style of play that Matt Eberflus once deployed in his time as the Colts’ defensive coordinator. Sit back in cover two shells, eliminate the vertical passing game, pressure the quarterback, and force turnovers. The Colts have forced seven turnovers in their past four games and they lead the league in fumbles recovered as a defense with nine this season.

The smartest aspect of this adjustment for Bradley is playing to the strengths of his linebacker group. Zaire Franklin and E.J. Speed are fine run chasers that can ROBOT back against play-action, but they are at their best playing downhill and attacking what is in front of them. This blitz-heavy, cover-two approach from Bradley has allowed the Colts’ linebacker duo (along with Grant Stuard in base sets) to be in attack mode on passing downs and get after opposing quarterbacks.

Even when the Colts are getting into some cover three looks, the secondary has shown fantastic growth this season in their zone recognition and assignment integrity. Nick Cross has developed some pretty good instincts this year and Jaylon Jones (despite the rough game on Sunday night) has flashed playmaking ability.

This interception by Cross might be one of the more instinctual plays in zone coverage from a Colts’ player the past few seasons.

There are even more wrinkles that Bradley has thrown in this season to hide the flaws of this defensive group, including mixing in three safety sets on passing downs to get more coverage players on the field. This unit still has some issues to iron out, but Bradley has done a good job adjusting to his personnel and finding an answer in this past month of play.

There is work to be done with this defense overall. Run defense is a bit leaky and some of the middle passing windows are far too uncontested for opposing offenses. That being said, there has at least been steady improvement on that side of the ball from the coaching staff and from the players on the field, something that can’t be said for the Colts’ offense in this past month of play.

Bradley may be the odd man out after the season, but he deserves credit for adjusting the defense after the Jacksonville disaster. His unit has been playing fast, hungry, and forcing turnovers in recent weeks, which has given the Colts’ offense a chance to win games. This is winning-caliber defense from Bradley of late, now it’s on Shane Steichen and the Colts’ offense to return the favor going forward.
