Dallas is 4-3-1, and that record makes them look worse than they've played. The 3 losses were all close, including 1-goal games against Pittsburgh and Colorado, and the Stars got the Avalanche back the next night in a shootout. They've also posted 2 4-0 shutouts in their last 5, at Buffalo and in Chicago, where they held a Blackhawks team that had scored 9 goals in 2 games since Connor Bedard's return to nothing. When this group keeps games low-scoring, it's hard to beat.
Boston's run comes with a bit of context. The first 2 wins of the streak were blowouts at home over Utah and Philadelphia, and the last 3 came on a West Coast trip through San Jose, Anaheim and Los Angeles. Dallas is the 4th straight road game. The 4-1 final in LA also looks bigger than the game was, since 2 of those goals went into an empty net after Khusnutdinov broke the tie late. This is a team winning the tight stretch of games, which is a better sign than the scores suggest and also a reminder that it hasn't been as easy as they look.
So it's Boston's offense against a Dallas defense that has been suffocating teams lately, and the Stars' depth is the thing being tested. The status of Hintz and Zacha is the news to watch between now and puck drop at 7:00 PM CT. If both play, you get a Bruins team that has rolled for 2 weeks against a Stars team that was showing up just as well before the injuries hit.
