No offense, but you seem to be so extremely rooted into this one belief without reasoning or analysis, it's hard to take you seriously.
You want reasoning and analysis? Very well.
He's clearly unable to play tackle at any sort of decent level in college, let alone the NFL. He doesn't have a center's body, which limits him strictly to guard. I highly doubt that he'll be able to function against quicker defensive tackles such as Atkins and McCoy or talented and/or athletic right/left ends that go on stunts against him. He has straight-line speed, functional strength, okay fundamentals, and can get to the second level in the running game. That's it.
His pass-protection has been terrible at Iowa, terrible against below-mediocre players such as the 3-4 defensive ends at Maryland, who gave him absolute fits in the passing game - both bull-rushing
and speed-rushing. It was one of the worst performances I've ever seen from a supposed "top-of-the-class offensive lineman", and he doesn't even have the excuse of using inexperience because that was his senior tape. He was a senior, and he got overpowered, overmatched, and beat like a rented mule by a 5'11", 285 lbs. 3-4 end on a horrific defense. What do you think that Kilgo (the nose tackle on the Maryland defensive line, and likely the only real talent that Maryland even had on the defensive side of the ball that year) would have done to him if Scherff was at guard? He's strong in the weight room, sure, but I don't see that strength translating to anything other than run-blocking.
He's extremely top-heavy (which allows bull-rushers to have their way with him), has horrible footwork (which allows speed-rushers to utterly destroy him), can't pull to save his life against quick one-gap penetrators such as Bennett (see OSU vs. Iowa), and he's just not a natural knee-bender like Peat is.
He'll be a guard at the next level, and probably not even a left one. He's not Zack Martin. Not even close because Martin - while he had issues at pass-protection - didn't get horrifically beat like Scherff did. He's not Reiff or Bulaga either. He compares more to his fellow Hawkeye alum, the #2 overall pick of the 2004 NFL draft: Robert Gallery. Gallery was also a weight room warrior and a much better overall athlete than Scherff. He couldn't hack it at tackle and carved himself out a career as a decent left guard. He's still regarded as one of the biggest offensive line busts in that decade (second only to Jason Smith).
But Scherff doesn't have Gallery's overall athleticism. He's strictly - in my honest opinion - a right guard. He'll be a decent right guard at the NFL level, but you won't ever see him make it to Pro-Bowls or the All-Pro teams. You can expect consistency and durability from him, sure, but you're not going to see him dominate NFL linemen. He'll give up more sacks than your average right guard, although he'll be a fantastic addition to the running game; that is, if you're asking him to just lock onto one guy and not have to pull to his left to stop a defensive end.
I would never criticize a prospect this much if I didn't watch a ton of tape on him or see a huge rap sheet. Scherff is a fantastic and an intelligent person, definitely worthy of being selected, but I don't believe for a
moment that he's anything more than a third round pick based on his film, and I don't believe for a single
heartbeat that we should draft him anywhere in the first two rounds. If you're looking at right guards, he's your guy; that is, if guys like Tomlinson are already gone.
Whatever he did in the Combine doesn't mean shit to me. Gallery and Smith blew up the Combine, too.
