NFL Comparison
Dak Prescott
Overview
Like Dak Prescott before him, Fields enters the league with dual-threat capabilities but is more of a pocket passer with the ability to extend plays or win with his legs when needed. He was up and down in 2020, but a bounce-back performance against Clemson -- including an impressive second half after suffering an injury -- said a lot about his toughness and leadership. He sees the field fairly well inside the Buckeyes’ quarterback-friendly offense but needs to become a full-field reader and prevent his eyes from becoming transfixed on primary targets. He sticks open throws with accuracy and velocity thanks to a sturdy platform and good drive mechanics. He’s also comfortable throwing into intermediate holes of a zone. A slower operation time and a lack of a twitchy trigger will require him to work with better anticipation and pressure recognition pre- and post-snap. He takes more sacks than coaches will be comfortable with but he also digs his way out of holes and creates explosive plays. Fields operates with a quiet confidence and has experience overcoming adversity. He should continue to improve and become a solid NFL starter within a couple of seasons.
