SportLogiq has Ottawa as the 19th best team in xG differential(total +3), while MoneyPuck saw them as the 15th best team at +5. Conversely, Boston ranks 17th by SportLogiq at +14, while MoneyPuck ranks them 20th at +3
The result is Ottawa having the third worst "goal differential above expected" by MoneyPuck – the impact of finishing talent and goaltending – while SportLogiq has them 7th from last, with a difference of 10.7 goals between the two values.
Similarly, there's a 10 goal gap between MP and SL's "differential above expected" for Boston, with MoneyPuck showing an extra 10 goals scored/saved
The last picture shows the "expected standings" from last year, where neutral goaltending and finishing for each team has Ottawa tied for 9th in the conference and 4 points out of the playoffs.
Ottawa is by no means the abysmal defensive team some make them out to be, but they're also probably worse than the public numbers show
