The Toronto Raptors are a flawed team, all NBA teams are. In a salary-cap league, every team has a set of weaknesses; you just hope they are fixable, or at least manageable.
Weaknesses can be fixed in one of two ways: You can excel in other areas to the point where it is not as relevant. — Last year Golden State ranked second from the bottom in DREB%. They still seemed to do alright. — Or you can actually improve in that specific area.
To fix a weakness, it doesn’t necessarily need to become a strength.
