Plot his USG%.
That's the number that was anomalous in the last 35 or so games (29 post-AS, 6 in the playoffs).
Over the course of his career, Green posted a USG% number above 20% only ONCE before last season. That was 21.2% way back in 2008-09, his 2nd year in the league. Other than that, the "consistency" over all those years up until last Spring was that his USG% was always under 20%.
Last season, Green posted a career-high USG% of 22.2%. But more telling is the breakdown over the season:
Pre AS: 20.9%
Post AS: 23.5%
By the end of the season, in April, it was up to 24.7% and it was 24.5% in the playoffs.
That's a very significant difference. The former number is a '4th option' player. The latter numbers are '2nd option' level usage (behind Pierce, who was around 27% most of the season.
Fourth option players get crappy end-of-shot-clock plays and with-a-prayer threes.
Second option players get actual plays called for them.
This (last Spring) was the first lengthy span in Green's career where he was getting '2nd option' level of usage. The vast majority of his career he was typically posting the 4th or even 5th USG% rate on his team.
A big question will be just how Stevens will use Green in his offense.
The thing I find unsatisfying about this argument is the assertion that higher usage caused better play in Green's case, rather than the other way around.
Why isn't it equally plausible - or even more likely - that his better play caused a higher usage rate, and a change in his role? Doc saw him playing better, so he gave him more shots and an increased role.
In which case Stevens can "use Green in his offense" however he wants, but Green's not going to reach the level of production/efficiency he attained in those 2-3 months, which were outliers relative to the rest of his career.
I don't think I stated that Green's higher USG caused better play in Green's case.
I'm pointing out that higher USG is what is correlated with his better play.
USG also very clearly tends to track a player's role in an offense. So a big change in USG is indicative of a big change in the way a player is being used. You can argue over whether the tail is wagging the dog or vice versa. I'm just pointing out that their is a wag.
If Doc played him more and he responded by playing better - that's good, right?
If he simply started playing better (perhaps because further removed from his rehab?) and so Doc responded by playing him more - that's also good, right?
Why does it matter which came first?
The thing I disagree with, is the contention made by many on this blog that a player simply "is who he is" after a few years as if context and role do not matter. As if how a player is utilized by his coach and his teammates doesn't matter.
It's not an easy thing to search for, given the nature of the search tools on most web sites. So I hesitate to assert just how common it is. But just anecdotally, this thread has already turned up several examples that show that a player's production CAN change dramatically with a change in context and/or role. Jackson, Johnson and Billups all experienced dramatic up-ticks. Wallace experienced sudden degradation in performance. Maybe he'll bounce back in this new situation?
It's also kinda strange how folks who want to dismiss Green's performance last Spring by averaging it into the entire season tend to completely gloss over the probable impact on his performance in the Fall that missing the entire prior season due to open heart surgery might have been.
This is a case where taking an average definitely obscures a lot of information.
