With a wide frame that can be challenging to navigate for run defenders, Mafi plays with good core strength, a broad base and well-placed hands to improve his power zone. Move blocking in the ground game and reactive adjustments in pass protection will create difficulties for him due to a lack of foot quickness. He plays with a chippy temperament that coaches will like. Mafi is scheme-dependent, but he has the potential to be a good backup or low-end starter.
