Left tackle at Ohio State is a job you earn, and Siereveld has held it without giving ground — zero sacks allowed across the 2025 season protecting the blind side of a Playoff offense. A 6-5, 325-pound fourth-year player and team captain, he has started at both guard and tackle, which is why ESPN slots him among the top 2027 interior prospects while draft boards list him as high as the No. 4 tackle in the class. That positional split is the actual evaluation: the NFL must decide whether his frame and movement keep him outside or make him a high-end guard, and the answer shapes his round. However, a minor procedure wiped out his spring, and a draft-year lineman can't afford a slow August ramp — the early-season tape needs to look like the 2025 version immediately. Everything on the record says top-100 pick; project a Day 2 selection in the 2027 class with starter expectations inside or out.
