Honestly Maroon's a big reason why I don't want to do the 4 and 4 method for protection.
Davidson's nice, he's a solid but unspectacular defenceman, and his minutes could potentially be replaced by Nurse, Reinhart, Oesterle, Simpson, Jones, Paigin... You get the point, the team has a ton of LHD.
Maroon is a guy you can plug into the top 6 to get a line to click, plus his cap hit is massive for this team in terms of giving flexibility. Toss in the fact he can be a beast on the ice, I don't want LV to get that kind of option. Also there's no one in the system that could replace him. (Khaira the closest, but he's more of a 3rd liner in upside)
