Offense Box Plus Minus - Luca Harden

In the regular season, Luca Donchich's offensive box plus minus numbers were 6.5, 6.4, and six. He has three straight years of being above six in that category. But his playoff numbers are actually still higher than Luca's in the playoffs. Do you think that that is telling us something here? That hardens a better offensive player? Is that just not a conversation you're particularly interested in?
