On the issue of obstructing MS, I can't help but think that is a bit silly to argue. Doesn't Irwin already block the iconic columns from the north and east (and won't Irwin surely be taller than this facility?)? When you drive down Fourth St, the columns are blocked by trees and the tarped fence around the practice fields. The view the new facilities will obstructing doesn't exist in the first place.
And I'm pretty sure that the only time those fences are not tarped is during the offseason, which is when you don't have masses of football fans that would theoretically need to be impressed by an unobstructed view.
