Trading Kulak for Poolman would free up $2.75 million in cap space, which could help the Oilers. However, the team is currently $7.2 million over the cap, so this move might only provide enough space to match one of the offer sheets.
Given the situation, the Oilers are likely to prioritize keeping Broberg, whom they drafted 8th overall in 2019. Losing Holloway, drafted 14th overall, for a 3rd-round pick would be tough, but it might be a reality the Oilers have to face. Broberg has played 81 games with the Oilers, scoring 2 goals and 13 points, plus 3 points in 10 playoff games last season. Whether Broberg or Holloway will stay with the Oilers remains to be seen.
