Here it gets a bit (a lot) more convoluted. Potential disrupts the perception of current ability, but potential should also affect current value. For an older player, performance over the duration of a season outweighs a strong finish, while for younger players, a strong finish could be a sign of long-lasting improvement. Players like Klay Thompson, Bradley Beal and Jimmy Butler all made dramatic improvements by the end of the season, but players like Arron Afflalo, Joe Johnson and J.J. Redick may have been better over the duration of the season.
At least at this moment, this third tier consists of the Joe Johnson, the oft-injured Eric Gordon, Arron Afflalo, J.J. Redick, Bradley Beal, Jimmy Butler, Klay Thompson and Manu Ginobili. Beal, Butler and Thompson all finished the season at a high level, Afflalo and Redick were consistently above average for mediocre to bad teams, Johnson was consistently above average for an above average team, Gordon was consistently not playing for a team and Ginobili was inconsistently excellent for a great team. All of these players have flaws, but all are, or at least by the end of the season appeared to be, a positive factor for their team.
