The Las Vegas Raiders' defense struggled significantly in the previous season, finishing tied for 25th in points allowed per game and 15th in total yards allowed. However, they've made substantial improvements this offseason, adding notable talents like safety Jeremy Chinn and defensive end Malcolm Koonce. Additionally, the Raiders are reportedly pursuing Justin Simmons, a free-agent safety, who could bolster their pass defense, which also faced challenges last season. Simmons' experience and proven track record, including two Pro Bowl selections, suggest he would be a valuable addition, especially at a reasonable market value.
