What's the reason for the scorebug not being at the very bottom of broadcasts?

I assume there is a legitimate reason, since it's consistent across the board.

My best guess is a safety net for different screen resolutions? But I'm very much ignorant on the matter


ABC



CBS



ESPN



FOX



NBC



It's like they leave enough room for a ticker to show scores from other games, but there's never a ticker. If you watch a CBS NFL game, it's the same format, but with a ticker that goes to the bottom. FOX is unchanged. ESPN MNF is lower, but not at the bottom. No ticker.

I might be acoustic.
