The Chicago Blackhawks are grappling with significant defensive challenges, particularly among their defensive pairings. Seth Jones and Alec Martinez have recorded the lowest expected goals percentage (xG%) on the team and rank third-worst across the league at 38.3%. Notably, changes in pairing configurations are needed, especially considering Martinez's decline and the struggles of other combinations such as Alex Vlasic with Connor Murphy and Louis Crevier. For the Blackhawks, returning Vlasic to play alongside Jones could help stabilize their performance.

Furthermore, rookie Nolan Allan and veteran TJ Brodie have emerged as the new worst pairing this season. With the Blackhawks' playoff hopes dwindling, it’s crucial to prioritize the development of younger players like Allan, while veterans should take a step back. The coaching staff must reflect on these metrics to improve the team's performance moving forward.
