If Danny cleared the logjam at SG(Turner, Bradley, Young, Hunter, at times Smart) and Derozan was the second piece we were adding, such as the first being Durant or Horford, then I wouldn't have a problem with the signing. But as a centerpiece of the off season, I wouldn't want Derozan. Just adding him to this currently constructed team would be a bad fit. This team needs shooters.
Now all that said, I see a lot of people stating that Derozan doesn't fit the system, but I don't see things that way. If we get a star or stars, it's going to have to be Stevens system that changes to maximize the abilities of his stars, not the stars adjusting to fit Stevens system.
