No, he’s not as good defensively as Anderson, but he is a better player. I like Anderson a lot too, should we downgrade him for not being able to contribute offensively or in the transition game like JC would? People on this forum (IMO) overrate defensive dman and underrate offensive ones.
If the Kings offered Anderson around the league would he return as much as JC? No, so that should tell you who is the more valuable asset.
A top 4 of Doughty, Chychrun, Anderson and Roy would be one of the best top 4’s in the league. There is some injury risk for sure, but there were risks with all the guys DL traded for as well. You have to roll the dice at some point.
