Isaac TeSlaa is turning a steady, training-camp rise into real NFL potential for Detroit. The third-round rookie has absorbed coaching at Allen Park, learned from veterans like Tim Patrick, and shown growth in both offense and special teams, while studying the game with Amon-Ra St. Brown, Kalif Raymond and Jameson Williams setting the pace.

TeSlaa heads to his first NFL game in Lambeau with big anticipation, stressing prep, film cutups and a readiness to make plays when called. He keeps a classic-rock and caffeine-driven pregame routine, and his interactions with Jared Goff have highlighted the quarterback’s command and leadership. The Lions plan to lean into his versatile skill set early, using his development as a barometer for the offense’s evolving depth.
