An even head-to-head record across multiple meetings is informative: it usually means neither team has a structural edge in the matchup that the market is failing to price. In a series like this the bet/ money split on each individual game tends to be the better signal than the standings — particularly when the gap between bet% and money% on the same side runs 10 points or more.
