Dekeyser starts 15 shifts in the offensive zone per game on average, while Smith averages 14. So while those are a different percentage of their actual shifts, Dekeyser should have more production to show. Youre also lying, considering Lashoff and Kindl both start more in the offensive zone than Smith. Excluding neutral zone starts, Dekeyser averages a massive 0.9% of his shift starts in the defensive zone than Smith per game according to extra skater. Smith starts 29.3% of his shifts in the defensive znoe while Dekeyser starts 30.2% in his own zone.
Dekeyser doesnt actually start that much more in the defensive zone at all, he has a much higher neutral zone start that explains the difference in their offensive zone starts. So while Smith does start in the O zone already more, they are both starting in the defenve zone pretty much the exact same amount.
So yeah, in other words their deployment really doesnt explain the difference either. Are you still sure theres that much of a difference or whats next on your agenda?
