ESPN's AFC South reporters weigh in on which player picked in Rounds 4-7 will have the biggest impact in the division. Each team's draft class is below the reporter's analysis.

Sarah Barshop, Houston Texans reporter: Colts linebacker Anthony Walker Jr. Despite the many additions on defense during free agency, the Colts still have an inside linebacker spot open with D'Qwell Jackson's release. Walker, Indianapolis' fifth-round pick, could compete for the spot. He was Mel Kiper's seventh-ranked inside linebacker in the draft class. Last season at Northwestern, Walker had 20.5 tackles for a loss. He also will help on special teams.

Michael DiRocco, Jacksonville Jaguars reporter: Jaguars receiver Dede Westbrook. He can make a significant impact for the Jaguars as a slot receiver and returner. That's a role Rashad Greene was supposed to fill, but he had a disappointing 2016 season and now will have to fight for his job. Westbrook was considered a top-50 player talent-wise, but slipped to the fourth round because of off-field issues. Westbrook caught 126 passes for 2,267 yards (18.0 yards per catch) and 21 touchdowns in two seasons at Oklahoma and won the Biletnikoff Award in 2016. He has the quickness desired of a slot receiver but also has deep speed. Westbrook returned only five punts in college, but he averaged 16.2 yards per return and took one back for a touchdown. If he can be the same kind of playmaker he was at Oklahoma -- and avoid further off-field issues -- the Jaguars will end up with one of the biggest draft bargains of 2017.

Paul Kuharsky, Tennessee Titans reporter: Titans linebacker Jayon Brown. The Titans felt like their man might disappear in the fifth round, so they dealt the 164th pick and a sixth-rounder (No. 214) to the Eagles to get to No. 155, where they drafted the UCLA linebacker. He should have a chance to replace Sean Spence, the veteran nickel linebacker who moved on to Indianapolis as a free agent. The Titans have been victimized by middling tight ends too often, and the speedy Brown will have a chance to show he can alleviate that issue.

Mike Wells, Indianapolis Colts reporter: Colts running back Marlon Mack. The Colts were able to wait until the fourth round before selecting Frank Gore's potential future replacement at running back. South Florida's Mack will help ease some of Gore's workload next season after the veteran had 199 more carries than his next closest teammate last season. Gore also turns 34 on May 14. A consistent running game with the Colts able to rotate between Mack and Gore will help quarterback Andrew Luck and the passing game. Mack left South Florida as the school's all-time rushing leader with 3,609 yards to go with 32 touchdowns.
