Again, "wind loading" and "weight" is PowerTuck cover story, for: Piecemeal and Cheap.
Sony Jumbotrons were extremely heavy, LED video boards are much lighter. Large speaker cabinets are essentially giant wind catchers and with huge PA speakers still inside they are extremely heavy as well. Take all of that out, and start over, instead Weiser would only pony up for taking out the old Sony JumboTron and installing a similar sized LED video board in the same frame, and putting in a new scoreboard beneath.
