Polzin gushed over Caleb Johnson’s landing spot, calling him a stylistic copy of Najee Harris who now gets to learn in the same offense. Pittsburgh spent low-end Day 2 capital, a signal they view Johnson as more than a change-of-pace back. Harris handled 287 touches last year, and with his fifth-year option looming, Polzin expects the franchise to lean heavily on Johnson’s fresh legs in 2026 – if not sooner should Harris struggle. The rookie’s size and one-cut vision match Arthur Smith’s downhill scheme, making Johnson a sneaky late-first dynasty pick who could vault into a 250-touch role within two seasons.
