High quality OLinemen were finally demonstrated even to the stupid media to be PRIME value in the NFL this year. Many teams failed in LARGE part because the OLine got injured. Schrauth is very high upside Guard quality (tough as hell, great hands, and big brains.) He'll get drafted and play.
As to our line: I believe that if healthy, Craig will stay at center. The staff seems to rate his ability to organize the line pre-snap very highly. Otting is probably also good at this, but the staff picked Craig over him this year and Coogan last. That part of the job is a big deal.
There is also a predilection of coaches to not shift positions if it's a close call. So, that would point to Knapp// ... // Craig// Lambert// ....
If THAT was true then assuming Jagusah is ready (I'm trying very hard to wish us a Joe Moore level line) he can go either place. If "five" is Black, then maybe Jagusah is in for Schrauth. If "five" is Abshur, then Jagusah is probably in for Wagner. The flip of him and Lambert in that option might be the estimate of whether guard or tackle is harder on the injured arm.
All of this is pretty ignorant on my part, but I write this just to indicate that I believe that this thing is really unsettled and complex, AND that it is likely that our OLine will kick ass whatever way we go. Jagusah MUST be ready if we're going to be REALLY elite though, and that means not playing with a still-risky arm break. He has to think that he can do everything he used to do in wrestling with that arm, because all of his body instincts are programmed with "just doing it" as a whole body in (violent) harmony.
