Lol than why exactly did we have a green guy like Broberg paired with the disaster that was Nurse during the finals if Bouchard could so easily turn that pairing into a ice tilting paring? Bouchard was a minus player until Ekholm showed up in March of 22. Show his statistics from before the Ekholm addition.
Because statistically, Ekholm-Bouchard was the most dominant pairing in the NHL this season, they're too good to split up. It wasn't that they specifically chose Broberg to pair with Nurse, it was the coaching splitting up Nurse and Ceci (the true disaster pairing this season/playoffs) which left Broberg as the guy to pair with Nurse as they were scratching VD. Broberg, when playing, had the lowest ice time per game at all strengths on the Oilers - he was the 6th d-man in the playoffs.
As for Bouchard's stats before Ekholm (oct 2021 - feb 2023), again he was part of 5 of the Oilers top 10 pairings (1, 3, 4, 5, 8) at 5v5 (50 min TOI) with Nurse, Broberg, Niemelainen, Barrie, and Lagesson - all >53 xGF% pairings. His pairings also represented 3 of the bottom 4 for OISV%, which there could be an argument made that he played a part in those numbers, however Barrie's pairings were 3 of top 4 (with same LHD options) and we all know how poor he was as a defender.
Broberg never had a quality veteran RHD to pair with, which is a failing of the Oilers org, however Bouchard has shown that he can tread water with sub-par partners.
