I think it is about the same odds that he will be a bust as it is that he will be an NFL 1st round pick like Wirfs. He has the size for sure, but he is definitely not a sure thing right now. I didn't ever see him in person, but his highlight tapes don't tell a whole lot because of the sheer size difference between him and the d ends he was facing. His technique in virtually all of his film shows him imposing his physical dominance by pushing down his opponent or throwing them out of the way, a technique you just don't see in college or pros because of the strength and quickness of the defensive ends at those levels. While he didn't wrestle like Wirfs did (which I think certainly develops a lot of leverage and hand fighting skills needed as an o linemen) he apparently plays basketball but I couldn't find any tape on that, so I have no idea how he moves in space. I will say that even before he committed to Iowa I did read some mixed reviews on people that saw him play football in high school, so that does say something too. So certainly no guarantee of a bust, but certainly no guarantee of a sure thing either. Only time will tell.
On a sidenote, and I will also say this about a player we did get: whether X and/or Proctor signed with Iowa was not really going to make a huge impact on the performance of this team. I am glad we have X, sure, and I wish we had gotten Proctor, especially at a position of need, but to me #1 impact would be QB, #2 would be a true X receiver that can beat man coverage and #3 would be an elite edge rusher like an AJ or Roth and #4 would be a space-eating defensive tackle. I think those positions when filled properly are the difference between an 8-4 type Iowa and an 11-1 type special team. So Proctor or no Proctor I think we will be serviceable on the o-line next year but the massive upgrade at QB will help that a lot, and, if we can be fortunate enough to get a true x receiver 2023 could be really really good. So hopefully they can take the NIL money that was dedicated to Proctor and get that x that we need so badly.
