I can say that I liked Matt Martin, Connor Brown, Nazem Kadri and Nikita Zaitsev, but we can't keep all of them because of salary cap. Matt Martin was wasted cap space for us with his contract. He was stop gap toughness during our rebuild to shield our younger players.
Islanders can afford overpaid grinders because they don't have Matthews, Marner, Tavares etc. They have Barzal though.
We can afford 800k physical grinder until playoffs any day and twice on sunday, because of injuries. Clifford isn't just tough ass grinder, he is also good possession player and character guy.
We don't know if Dubas made this trade with Kings more so for Clifford or Campbell, but we can guess that it might have been for goaltending. If so it would be bold to assume that Dubas made 180 degree turn, because of Kyle Clifford. I think he was suitable and available player that fit the bill for us.
Kind of dream come true player for us fans, because his one of rare breed. Physical beast that can fight and play hockey. I don't think he'd fit our long term plans, but nice addition for this season.
