Posted: Thu Oct 11, 2007 9:11 am Post subject: Players likely to get better or worse
From a secret formula, I've analyzed 138 current player careers for their tendencies over the last 5 seasons. A few careers of 3-4 years are considered, for premier players. I didn't use age as a factor; whether a player is 25 or 35, if he's gotten better (or worse) each of the last 5 years, the formula predicts same next year.
Here are players to avoid, as their careers seem to be falling off the table. Some have already hit the floor, but they might yet appear as fill-in material; listed in order of productivity loss expected (as a decimal fraction):
Code:
-.285 Kenyon Martin
-.283 Gary Payton
-.254 Michael Olowokandi
-.243 Clifford Robinson
-.240 Aaron Mckie
-.212 Lorenzen Wright
-.202 Jeff Mcinnis
-.197 Theo Ratliff
-.197 Malik Rose
-.178 Raef Lafrentz
-.163 Stephon Marbury
-.157 Jalen Rose
-.154 Antoine Walker
-.143 Andrei Kirilenko
-.136 Shareef Abdur-Rahim
-.133 Eddie Jones
-.133 Marko Jaric
-.130 Eric Piatkowski
-.125 Kurt Thomas
-.123 Steve Francis
-.119 Kenny Thomas
-.116 Corliss Williamson
-.113 Donyell Marshall
-.111 P.J. Brown
-.109 Brad Miller
-.105 Jamaal Magloire
-.103 Kelvin Cato
-.103 Desmond Mason
So all these players are expected (by the magic formula) to produce 10-28% less in any minutes in which they may appear. (I realize some have announced retirement, and others do not appear on any roster; but you never know.)
Some of these guys weren't big producers to begin with, so here they are by magnitude of loss. I'll go ahead and scale to PER loss (roughly), relative to 2006-07:
Code:
-2.7 Kenyon Martin
-2.6 Gary Payton
-2.2 Stephon Marbury
-2.0 Andrei Kirilenko
-1.8 Kevin Garnett
-1.7 Lorenzen Wright
-1.7 Malik Rose
-1.7 Steve Francis
-1.7 Shareef Abdur-Rahim
-1.6 Raef Lafrentz
-1.6 Clifford Robinson
-1.6 Aaron Mckie
-1.6 Antoine Walker
-1.6 Michael Olowokandi
-1.6 Jalen Rose
-1.5 Donyell Marshall
-1.5 Theo Ratliff
-1.5 Jeff Mcinnis
-1.5 Eddie Jones
-1.4 Brad Miller
-1.4 Kurt Thomas
-1.3 Richard Jefferson
-1.3 P.J. Brown
-1.3 Shaquille O'Neal
-1.3 Kenny Thomas
-1.2 Allen Iverson
Now here are the big gainers to look for, in PER-ness:
Code:
2.3 Josh Howard
2.3 Dwyane Wade
2.1 Dwight Howard
1.9 Manu Ginobili
1.8 Chris Bosh
1.8 Carlos Boozer
1.8 Tony Parker
1.6 Emeka Okafor
1.5 Yao Ming
1.5 Steve Nash
1.4 Lebron James
1.3 Carmelo Anthony
1.1 Dirk Nowitzki
1.1 Joe Johnson
1.0 Gilbert Arenas
0.9 Caron Butler
0.9 Nazr Mohammed
0.8 Marcus Camby
0.7 Mehmet Okur
0.7 Drew Gooden
0.7 Zach Randolph
Predicting whether a guy has peaked already is key here. For Steve Nash, I would've predicted that last year, and the year before, and the year before.
As a % of improvement expected:
Code:
.066 Josh Howard
.056 Dwight Howard
.052 Dwyane Wade
.051 Chris Bosh
.049 Emeka Okafor
.045 Manu Ginobili
.045 Tony Parker
.042 Carlos Boozer
.039 Steve Nash
.037 Carmelo Anthony
.036 Joe Johnson
.034 Yao Ming
.033 Lebron James
.032 Caron Butler
.031 Nazr Mohammed
.028 Gilbert Arenas
.028 Lindsey Hunter
.025 Dirk Nowitzki
.025 Ruben Patterson
.023 Marcus Camby
.023 Mehmet Okur
.022 Drew Gooden

for the most part i'd say your magic formula is dead on, with just a couple of exceptions:
- i'd swap nazr mohammed to your loss in productivity list. of the 260 players to have played at least 2000 total minutes the past two seasons, he's got the 2nd highest rate of fouls committed (16 fouls per 100 minutes played), and he'll be 30 years of age in 07-08. also his turnovers per touch were the highest of his career the past two seasons since his first two years in the league. unless antonio mcdyess or rasheed wallace gets injured, i doubt he plays even 20 min/g in 07-08 (he did however play 28 min/g for the knicks in 04-05 when he fouled much less)...
- zach randolph will be sharing the low post with eddy curry in 07-08, after having been the blazers main low post threat last year and shooting better than he had in four seasons. thus in 07-08 he may suffer a significant drop in FG% like channing frye did in 06-07 compared to 05-06. in 05-06 curry and frye mostly split the C minutes, and frye shot more from in close to the basket than in 06-07 when curry played 81 games and 35 min/g at C and frye played C/PF...

According to 82games, Randolph was already taking 59% of his attempts as jump shots last season, anyway. My memory (having watched 75-80 Portland games) confirms that as accurate. He is still an effective post player, but his elbow-and-out face-up game is just as important to his arsenal now. I think he'll be fine next to Curry.

if you look at mr. randolph's 82games.com stats, his inside eFG%s the last 3 seasons have been pretty consistent, between 54%-55%. but his jump shot eFG%s were at just under 42% last season and below 39% each of the previous two years. last year his overall eFG% was 47.2%, which was 2.6% less than just the league average of 49.6%, and that was his best eFG% in 3 seasons. in 04-05 and 05-06 his eFG%s were more than 3%-4% less than just the league average eFG%...
i'm guessing that if in playing alongside eddy curry he ends up taking a higher percentage of his total FGA from outside compared to inside than he has in the past (which could very well happen if curry remains the knicks' primary low post threat), that his eFG% is going to go back down. plus even though he has gotten fouled alot and hit his FTs at close to 80% these last 3 seasons, his overall shooting or ScFG% these 3 years has still not been as good as even the league average overall shooting, primarily because while the average 2pt FG% for PFs the last 3 years has been 49%, randolph has shot less than 46% on 2s...

Yes, there are cases -- some more obvious than others -- of players who should not be expected to continue their 5-years trends. I don't really expect Nowitzki, Boozer, Parker, Nash, Camby, Zach, or Nazr to continue rising another year. But they might.
I was just using a trend analysis, irrespective of context. If, rather than being traded, the Blazers had decided to build a team around Randolph (and drafted Durant?), then his 'PER' improvement might be even greater than this modest couple of %.
The point is that players are going uphill in their career trajectories, until they aren't. Steadily down is seldom reversed.
Mohammed is one kind of anomaly. Five years back, his career kind of bottomed out. He's improved every year since (in T rate), or in 3 of 4 years (PER).
He's a steady 15-12 (per40) guy; last 2 years he shot 56%; 2.2 TO/40 is hardly alarming. He fouls way too much to get minutes, but PER doesn't care about MPG. _________________ 40% of all statistics are wrong.

Yeah, I wasn't suggesting Randolph has been an efficient scorer (and so will continue to be one), just that I am not certain his game will have to adjust to Curry all that much. Even among his inside field goal attempts, a lot of those came from beating his man after facing up, not necessarily from occupying the low block, where we agree Curry will be most of the time.

Predicted PER change from last season to the upcoming season. I didn't study individual circumstances. Even though I think Wade's PER was overblown last year, his trend is still upward.

Missed this earlier. You mean like, do players (of a given type) tend to stop improving (or drop off) at a certain age? No, everyone's different, until they prove otherwise.
Anyway, I should have a more comprehensive listing coming along shortly. _________________ 40% of all statistics are wrong.

Having now looked at 301 current careers (of at least 2 seasons), another list. There's a lot more uncertainty in a 2-year 'trend' -- which amounts to just projecting last year's T-Rate improvement to next year's -- and so I'm just going to separate out 2- and 3-year careers. 4 years isn't a lot different from 5, so they'll be lumped in together.
From the 4+ years group, the biggest expected improvers, in the MikeG T-rate (no longer 'scaling' to PER):
Code:

2.4 Lebron James Cle 40.8 43.1 1.06
2.3 Carmelo Anthony Den 34.6 36.9 1.07
Sticking to my guns, so to speak, I'm not subjectively saying 'Nash won't keep improving', or 'Dirk doesn't look that good'. These guys are still on the upswing. If everyone improves these amounts, teams will average 42.6 wins!
Here are 3-year players whose 4th is expected to be better:

By popular demand, players whose 4- and 5-year histories suggest downturns in productivity. Again, no outside influences are considered. As in the list above, players are listed with their 2007 teams. I've omitted players who do not seem to be on any roster at this time.

A number of these guys have gone to other teams. I'm not expecting to see Payton, EThomas, Fortson, Cliffy, McKie, Kandi, JRose, JakeT, Wesley, and Corliss.
Since younger players tend to get better, there are relatively few resisting that trend. Players with 3 and 2 years of experience, who have regressed in their short careers:
