Full Scouting Report
Austin Siereveld is a very solid offensive line prospect. Most of his snaps this season have come at OT, so he is a little tougher to grade. I based my grade on what I could see through the first 4-5 games of the season. Siereveld was a 3-star prospect coming out of Ohio. He attended Lakota East in Liberty Township, Ohio. Siereveld ranked 16th in Ohio in the 2023 class. Siereveld had offers from Ohio State, Alabama, Cincinnati, Georgia Tech, and Illinois, just to name a 5 out of the 16 he had. He decided to stay in his home state and go to the best athletic program in the state. Most scouts expected him to move inside in college, even though he has played a lot of snaps at tackle.
Austin Siereveld has had a very solid season, but there were some lowlights. Siereveld has a very solid frame for the position. He has a thick build and stands at 6’5” I am unsure about his arm length or hand size. Siereveld moves slightly above average for his height. He can reach second-level defenders pretty well. He can also get out and move well on guard pulls. His footwork isn’t easy to grade since he has been playing tackle a lot. His footwork at the guard position is much better than at OT. He can mirror defenders decently well. Siereveld replaces his hands very well and tends to rely on that. He possesses very heavy hands that can completely halt a defender's momentum if he locks on to you. Siereveld’s best trait is his strength at the POA. He effortlessly moves defenders to wherever he wants. Siereveld has an incredibly strong base that can handle the bull rush with ease. He pairs that with good hip torque and leg drive. Running the ball to his side is a good idea if you are the offense. The Ohio native can almost always open a running lane for the Jacksons. He brings a good amount of physicality to the table. He shows good hustle plays to the whistle and will bury you if he can. Siereveld is probably the smartest IOL I have scouted recently. He finds a way to slow the game down. He is always looking for extra work, passes, and receives assignments very well. Siereveld also offers a ton of versatility. He has played OT for one of the best programs in the country and held his own while also being a top guard prospect in this year's class.
Siereveld does have some weaknesses. I am not as high on him as other scouts seem to be. Siereveld lacks the athleticism and elite length to be a first-round pick to me. He has very stiff hips, which make it nearly impossible to recover from mistakes. His footwork at the tackle position is a mess. If he faces a quicker guy, he has no chance. Mostly because his hand timing and placement aren’t perfect. That results in him whiffing and having zero chance to recover. I do believe he has gotten better and more acclimated to the position, but he is still shy of being an NFL-caliber tackle. I think for him to succeed at the next level, he has to stick to guard or center. I also see scouts rave about his physicality, but I simply don’t see it. I don’t think he matches the physicality of Vega Ione or Rutledge, who were both first-rounders last season. He definitely has above-average physicality; I just don’t think it is as good as people think. Siereveld can also be a little late to see blitzes at times.
Siereveld will be 22 by the time he is drafted, which is definitely reasonable. He did have some minor injuries following the 2025 season and in the preseason leading up to this season, but nothing has really been publicly disclosed. Overall, I like Siereveld, and I think he will be a good guard at the next level; however, I don't think he is worthy of a first-round pick yet. I think he would be a good fit with the Packers, Bengals, Jets, Titans, or Raiders, all of which have struggled to generate running lanes for their running backs. I could also potentially see the Seahawks. However, I think the first 5 teams fit his profile best.
