and defensive ratings were 102.2 and 97.8 last season, resp. This
year, they are 98.9 and 97.7 (roughly, thru 2/17). The big decline
is in the offense. [Technically, having done estimates of
possessions this year and checked against games, it could be that
this year's ratings go up about 1% due to inaccuracies in the 0.4
multiplier in the formula. Doesn't change the story, though.]...."
sure...make me eat my words.....my humbliest apologies, you are absolutely correct. my diatribe on the 76ers was a surficial look (without objectively looking at the data - no excuse however) and i was wrong, and i should have known better (didn't stop me tho!:)) . after looking at the numbers (using doug steeles data for this season), i come to the same conclusion. last year the 76ers scored 1.023 pts per team possession, and gave up 0.983 pts per opp team possession. this year their offense is down to 1.002 pts per team off possession, but the defense is close to last years mark at 0.988 pts per opp team possession. this year's defense is slightly worse than last year's, but the offense is significantly worse - the defense is up .005 pts/poss but the off down .021, four times worse. without looking at the individual player data yet tho, can't say why this is...
as for iverson i still believe (subjectively, not objectively) that he is a worse than average defender for an SG, not including steals or blocks, i.e. when it comes to denying his man the ball, preventing him from scoring, etc. - based on what i've seen. he was definitely (again opinion) the 76ers worst defender of last years starting five (snow, he, lynch, hill, ratliff/mutombo), but would love to be convinced otherwise. do you have any data showing otherwise...

the 4-1 model: Like Bob Cousy, who didn't do defense,
since he had Russell in the last half of his career.
Bird, of course, had Robert Parish.
I suspect there might be some minor exceptions (Jerry
West, Jason Kidd, Gary Payton, Bobby Jones, Dennis
Johnson, John Havlicek, etc.) who might provide a
benefit beyond the 4, but overall my intuition says
your model would fit pretty well. And of course the
model would probably need to be stochastic if you're a
real stickler, but a simple discrete 4-1 model I bet
would do a pretty decent job. (I'll bet a nickel.)
