This prop means that the team chosen must win both halves of the game.
Each half is considered to start at 0-0.
Team A vs Team B
I choose Team A to win both halves
The score after the first half is:
Team A – 2
Team B – 0
The score after the second half is:
Team A – 3
Team B – 3
This means that Team A only scored 1 point in the second half and Team B scored 3 points.
My bet would be a loss.
Note: If there are no scores in the first or second half, my bet would also be a loss.
