Free agent defensive lineman Dontari Poe's market has been slow to develop due to "concerns about his back," according to ESPN's Ed Werder.
Poe received surgery to repair a herniated disk in 2015 and continued to struggle with back issues throughout last season. Werder did add that he's asking for a lot of money, so that's likely a contributing factor as well.
The Kansas City Chiefs finished 10th in opponent-adjusted Defensive Net Expected Points allowed per play last season with Poe as the anchor.
