Larsson is a 6'3» right shot defensive defenceman, the type of player who could excel in the playoffs. After playing 838 career NHL games, Larsson has only played 38 games in the playoffs - including a few short runs with the Oilers. With his play style and familiarity with the team, Larsson would've been a great candidate for the Oilers to re-acquire for the playoffs.
Larsson did leave Edmonton after he suddenly lost his father to a heart attack while he was visiting, and he was looking for a fresh start in a new city after the incident. It feels unlikely that Larsson would've accepted a trade to Edmonton had they tried to trade for him.
