The Bruins won huge in Game 3 (7 to 2 final) but all the scoring was thanks in large part to Boston going 4 for 4 on the power play. As a result, this O/U is back up to a 5.5 for Game 4. Per the simulation report, this has resulted in a value play on the under in this one. The Blues can not allow so many power play opportunities, and also much play much better defense in front of goalie Jordan Binnington. Look for a much tighter and low-scoring game after the wild Game 3 results. The O/U is 8-16 this season when Boston is in a road game where the total is 5.5 goals. In this post-season, when leading in a playoff series, the Bruins O/U is 1-5. After a loss by 2 or more goals in their prior series, the Blues O/U is 8-15. When trailing in a playoff series, St Louis O/U is 1-5-2 the last 8. Just one over in eight occurrences! Per the above as well as the simulation report, play UNDER
