BYU’s Strantz Mangisi: a 6-foot-4, 300-pound redshirt freshman with room to boom
Mangisi enters the 2026 season as a 6-foot-4, 300-pound redshirt freshman offensive lineman for BYU, and the early read is simple: he’s a developmental tackle/guard type with real frame, local roots, and upside if the technique catches up to the body. BYU’s roster and recruiting notes list him as a Provo native who chose the Cougars over other PWO options, and his weight has trended down about 10 pounds since 2025, suggesting a focus on conditioning and mobility. That makes him an intriguing fit for a program that values physicality, depth, and long-term line development.
