The lower level in that picture looks like it could seat what? Possibly 20-25,000. That's not an unreasonable place to start. Build the lower level horse-shoe to include all of the locker rooms, weight rooms, video rooms, study rooms, training rooms, etc. And it looks like there is an open plaza inside of those arches. I am sure that the whole second level is more of a best case scenario of what could be added on someday. And having a covered plaza would sure be nice on those inclement weather days.
I doubt showing these plans to potential recruits would really hurt either.
