Mercedes-Benz Stadium officials are proud to claim the largest video board in sports, but their boss acknowledges he worried it might be too large.

“That was a silent concern that I had,” Arthur Blank, owner of the Falcons and Atlanta United, said. “I saw it going up in the building, the skeleton of it, and I said to myself, not out loud, not publicly, ‘This is really big.’ But when it was in full motion and completely activated … I thought the proportions were perfect.”

The oval-shaped video board, which rings the opening below the retractable roof, is sure to command attention when the stadium debuts with a Falcons exhibition game Saturday night.
