This idea of how much Kevin Love is worth being had in a vacuum. Love is an elite player but not a complete player. Can you be a superstar worth max level and not be a complete player? Sure you can: Nash, Magic, and Bird were pretty awful defenders, Shaq FT's had a negative impact at crunch time etc.
You have to take it he is young, just entering his prime, and despite his defensive problems is easily top 5 in his position in multiple categories (scoring, shooting, rebounding, passing). On top of that, currently he is not being matched with personal that complement. Sort of like Lebron had to play with terrible shooters like Hughes and Snow because of the lack of talent. Love with a decent rim protecting C is another story. Last year the Wolves when they added a decent but not exceptional player in Dieng suddenly their defense jumped. Between Haywood's contract and the Memphis #1 we have the assets to solve the problem***
***It's funny that Dirks' name is bandied about so much: he would have completely different rep had Dallas not stumbled into Chandler.
