It is saturday and time for all those many college football games
and you are likely lined up on a couch or at a friend's house or somewhere watching the games on TV --
And doubtless you have noticed that, in addition to the normal white lines marking off each 10 yard segment, there is a Yellow Line (and often other lines) added to the TV screen to help you know where the key points of the play are to take place.
These additional lines are not on the field in 'real life' as those of you who go to the games in person have noticed.
But they are on the TV version and are really helpful.
So, how do these lines get there? What is the science behind them?
A friend of DIT found this video which explains how it is done. Thanks friend.
HERE'S THE LINK to those yellow lines in TV football games
