Because they’re cheating mofos for some sick reason

Boston Celtics 1Half
2half Milwaukee moneyline

If Boston wins the 1st half, Milwaukee will be prohibitive favourites in the 2nd.

If you mean Milwaukee on the spread or just live to win the game, that seems more sensible. 3rd quarters have been a major issue for Boston.
