Detroit Lions training camp observations, Day 1: New players, new roles

Key Points:

• The Detroit Lions began their 2026 training camp with a 90-minute practice involving 86 of their 90-man roster, with key absences including superstar running back Jahmyr Gibbs, possibly due to contract extension talks.
• On offense, Sione Vaki impressed with pass blocking and blitz pickup, earning first-team reps at running back in Gibbs' absence, while Jackson Meeks officially transitioned to tight end, focusing on blocking and competing for a roster spot.
• The right tackle position features a competition between first-round pick Blake Miller, who took all first-team reps, and Larry Borom, who practiced at multiple line positions, indicating versatility in the battle for the starting role.
• Defensive depth saw veterans Avonte Maddox and Chuck Clark starting at safety, with a notable cornerback competition between D.J. Reed, Ennis Rakestraw, and Rock Ya-Sin for the CB2 spot, while rookie Jimmy Rolder earned second-team reps at linebacker's MIKE position.
• Edge rusher Ahmed Hassanein shifted to a "big end" role, benefiting from a significant body transformation and coaching support, aiming to leverage his power and athleticism to secure a roster spot alongside Tyler Lacy.
