Marquez Valdes-Scantling (MVS), who signed with the Buffalo Bills after two Super Bowl-winning seasons with the Kansas City Chiefs, is reportedly on the roster bubble as he struggles to connect with quarterback Josh Allen during training camp. According to Joe Buscaglia of The Athletic, MVS has 'faded into the background' and has not made a strong impression in drills, leading him to work primarily with second-team players. The Bills' wide receiver corps is highly competitive, with Khalil Shakir, Curtis Samuel, Mack Hollins, and rookie Keon Coleman reportedly ahead of him in the pecking order. Additionally, MVS's past performance has not been as impactful, having recorded only 21 catches for 315 yards last season. Meanwhile, rookie safety Cole Bishop is seizing opportunities due to an injury to Mike Edwards, gaining traction in the Bills' defensive lineup. Coach Sean McDermott has noted Bishop's improvement, particularly in mastering the defensive scheme and communication.
