Some players, like Tatum, Markkanen, Fox, etc. have gotten better as the season progressed. Smith has gotten worse, and that's why he's fallen. I don't think he's a particularly good fit on the Kings. He's a pretty ball dominate player, who has a questionable three point shot. If he's sitting there and I have to choose between Smith and Fox, I'm taking Fox, or Monk, or Markkanen. There are two types of fit. One is a need at a particular position. The other is a need of players that can, or are willing to play a certain style of basketball. Smith fits one, but not the other. At this point, I think getting players that fit the style of play that you want to play is more important than they fit the position you need.
Having said all that, I do think Smith is going to be a good player in the league. He's too talented not to be. He just strikes me as one of those players that's not willing to work hard enough to get to that next level. Of course it's just my opinion and I've been wrong many times.
