Kansas City Chiefs training camp primer

New faces: DE Frank Clark, S Tyrann Mathieu, DE Alex Okafor, DE Emmanuel Ogbah, RB Carlos Hyde, CB Bashaud Breeland, LB Darron Lee, LB Damien Wilson, S Juan Thornhill, WR Mecole Hardman, DT Khalen Saunders They're gone: OLB Dee Ford, OLB Justin Houston, S Eric Berry, C Mitch Morse, DT Allen Bailey, CB Steven Nelson, TE Demetrius Harris, WR Chris Conley, RB Spencer Ware, S Eric Murray, S Ron Parker

2019 snapshot: The team that came thisclose to a Super Bowl appearance didn't rest on its laurels, instead churning the coaching staff and roster, particularly on defense. Steve Spagnuolo replaced fired D-coordinator Bob Sutton, while Clark, Mathieu and Okafor/Ogbah step in for departed Pro Bowlers Ford, Berry and Houston, respectively. At best, those changes feel like a wash, especially because Clark and Mathieu have higher salaries than their counterparts (and acquiring Clark cost Kansas City its first-round pick).

The defense added enough talent to improve, depending on how quickly the group clicks under Spagnuolo, but there are still concerns. Unless Breeland returns to his form from Washington, cornerback remains a question mark. There's also no dangerous edge-rushing threat other than Clark. Chris Jones could hold out while seeking a massive extension entering a contract year, and locking him up is imperative after trading Ford and releasing Houston. The Chiefs caught a break when Tyreek Hill avoided league punishment following a child and family services investigation. The pick of Hardman (second round) provided some insurance, but Hill's role as a centerpiece in Andy Reid's offense would have been impossible to fill if he missed time. The offense made few other additions while losing its starting center (Morse) and a few role players, and all numbers suggest at least slight regression from 2018's heights.

--Patrick Mahomes' sudden stardom makes the Chiefs an annual favorite for double-digit wins. Taking the over on 10.5 wins always carries risk, but this team is a good bet. --Battling voter fatigue and year-to-year regression, only Peyton Manning (who did it twice) has won back-to-back MVPs since 1996. We'd steer clear of Mahomes' +450 odds (best by 200) to repeat.

Bottom line: The Chiefs clearly worked to improve on defense, but the upgrades appear marginal for now. They remain Super Bowl contenders but might have to keep winning shootouts.
