Scouting Report: Weaknesses

• Tall frame creates leverage issues against low-pad-level defenders who can get under his chest
• Run blocking consistency wavers - looks dominant one snap then gets stalemated by smaller defenders
• Weight distribution sometimes shifts forward when climbing to second level causing whiffed blocks
• Play strength against true power rushers remains questionable despite his anchor improvement
• Needs to develop more violence at the point of attack - too often settles for position blocks

Scouting Report: Summary

The tape shows a fascinating dichotomy - Tiernan dances through pass sets like he's been doing it for a decade, yet sometimes looks like he's learning the run game on the fly. Watch him mirror elite edge rushers and you'll see a tackle who understands angles, timing, and hand placement at a veteran level. His ability to absorb power rushes without giving ground makes you forget he's still developing physically. But then the next series starts and he'll get walked back by a 270-pound defensive end on a power run, leaving you scratching your head about his functional strength.

His basketball background jumps off the screen in space - the lateral agility and body control allow him to handle stunts and late blitzers with ease. Northwestern asked him to handle an island role against the Big Ten's best, and he rarely needed help. Yet that same movement skill hasn't translated to consistent displacement in the run game. He'll seal the edge beautifully on outside zone one play, then fail to generate any push on a simple down block the next. The technique is there, but the violence and leg drive remain inconsistent. His frame suggests more bad weight could be added, though his current mobility might suffer.

Sunday readiness depends on scheme and expectations. The pass protection translates immediately - he'll handle NFL speed rushers from day one with his patient sets and active hands. Run game development becomes the swing factor for his ceiling. He won't embarrass himself between the tackles, but opposing defenses won't fear his run blocking either. The modern NFL values blindside protection above all else at tackle, and Tiernan delivers that in spades. Whether he evolves into a complete player or remains a passing-down specialist will determine if he becomes a perennial Pro Bowler or just a solid starter. Either way, somebody's getting a tackle who keeps their quarterback upright.
