From Daniel Jeremiah at NFL.com:
Zabel is a versatile offensive lineman with excellent toughness and awareness. He lined up at left tackle in 2024, but he has played four O-line positions during his collegiate career. I believe he’s best suited to play guard at the next level. In pass pro, he has quick feet, stays square and catches/absorbs rushers. His lack of length shows up on the perimeter. He allows defenders to capture his chest, but he still possesses the core strength and balance to stall their push. He shows the savvy to snatch rushers when they get overextended.
