I completely disagree with the premise of the article that draws are most boring and the wider the score difference the more interesting the game is.
Frequently draws are very exciting, they can make compelling viewing. In a game that is completely dominated by one team, there can be very little of interest.
An alternative metric would be the degree of uncertainty/jeopardy in the game. So a game that ends 1-1 has a high degree of jeopardy because at any moment a team can score and take point from the other team.
