Spencer Brown

Brown's big-frame, right-tackle work benefits from rare continuity with Torrence. He can be a road-grader in the run game while using that familiarity to keep the edge secure for Allen.

Strengths: Size, right-side continuity, run blocking and accumulated starting experience.

Weaknesses: Longer tackle body can be stressed by quick edge rushers, requiring consistent hand placement and footwork.

Brown has grown from a fascinating small-school athlete into a real NFL right tackle. Sixty-nine starts, a huge 6-foot-8 frame and a stable partnership with Torrence give Buffalo a dependable physical right side. He lost some time to shoulder trouble last year, but returned for the playoffs. A seven feels right: the ceiling is still attractive because of the size and movement, while the next level is cleaning up technique against the very best edge rushers.

Strengths: He has rare length, strong run-blocking potential and extensive starting experience. Brown can create movement at the point of attack and has improved his confidence and consistency through a heavy NFL workload.

Weaknesses: Long limbs can create leverage and hand-placement issues, particularly against fast counters. Shoulder health and occasional pass-protection lapses keep him from the most reliable tier of tackles.
