Strip the book's cut out and the market calls this a coin flip. Nothing in the price separates these two, so the pick is whichever side you can get a better number on. On the total, the over is the cheaper side of 8.5 at the posted prices. The projected score is the posted total split by that win chance — a market projection, not a model of ours. Our own side on this game, if we take one, goes out in the newsletter before kickoff.

Win chance (no-vig)52.2%47.8%
Break-even at the price54.5%50.0%

Both posted prices together imply more than 100% — that surplus (4.5% here) is what the book keeps. Strip it out and the market makes this BOS 52.2%, BAL 47.8%. The break-even row is the win rate you'd need at the posted price just to tread water — the gap between the two rows is the cost of the bet.
