Highly experienced college tackle who is likely to kick inside due to a lack of length that affects his protection projection. Tiernan is tall but carries the denseness of frame and core strength of a guard. Feet feature good initial quickness and he takes excellent angles on the move. He often finds early positioning advantages as a base blocker but lacks the anchor and play strength to consistently fortify/sustain. Leaky edges in pass pro will be less concerning with smaller spaces to patrol, while his punch timing and lateral quickness provide advantages. “Solid” feels like the ceiling for Tiernan as a guard/swing tackle who can eventually elevate into a starting role.
