impressive rebuttal. so beyond your obvious attraction with the "eye test" (and who can blame you with that hair??), which you adamantly prefer to any sort of measurable success rate, what true value are you adding to this conversation? I know you don't like looking at n=2, but that's all there is in this series, and through these 2 games, he's been the 2nd worst offensively and defensively rated player, while having the highest usage rate.
As i see it, there are 3 main paths for him to take going forward (this isn't an argument of why he isn't doing some things, or how he can start doing so, merely an exercise on how improving the play of our highest usage player impacts us).
Option 1) He starts scoring and defending more closely to the way he did through the season == high efficiency, high usage, team == net gain in efficiency
Option 2) He plays as he has been, but he drops his usage rate AND someone else uses the possessions with greater efficiency == low efficiency, low usage, team == net gain in efficiency (from another player)
Option 3) He keeps his team-high usage rate, and still struggles to score or defend, and barring a miraculous return from Rudy, probably lose the series == low efficiency, high usage, team == net loss in efficiency.
winning this series boils down to him bringing up that 2nd worst -4.4 OBPM, team worst -3.4 BPM, team worst VORP, 2nd worst win share rate, and 2nd worst true shooting %. If he's going to use more possessions than anyone else on the team, those possessions can't be so inefficient.
