Sportsbooks may incorporate biases or seek to profit from public perception, while this market aggregates diverse opinions.

It’s important to note that discrepancies can emerge due to differing risk assessments and the nature of how each venue sets its prices. Examining both can provide a more comprehensive view of potential outcomes.
