Kastelic notched a trio of assists in a 4-3 loss to the Panthers on Monday.
Kastelic already has five points through the first four games of the season. At this rate, it won't be too much longer before the 25-year-old center tops his personal-best 11 points from back in 2022-23 when he was with the Senators. Still, a bottom-six role without power-play opportunities will limit Kastelic's ability to continue to produce with consistency the rest of the way.
