The Rams operate a pro-style offense featuring power run concepts, play-action passing, and a strong emphasis on protecting the football from turnovers.
Initially a valuable clipboard holder and practice arm, Mannion's ceiling is that of a high-end backup who can execute a conservative game plan if pressed into service.
Spread-option or run-heavy RPO-based offenses that require a mobile quarterback to extend plays or consistently escape pressure.
Mannion's limited mobility and arm strength dictate a role in systems prioritizing timing, accuracy on intermediate throws, and a strong running game.
Selected #89 overall in Round 3 of the 2015 NFL Draft by St. Louis Rams out of Oregon State.
