    Dude, why do I even bother posting...when you are always a step ahead of me..:D ...great post Codell...Too bad your efforts will probably be in vain since most Cat and Steve lovers will never understand the term team chemistry. Or that feeling when you get when you know your teammates are with you 100% on both end of the court.

    After some thoughts about it, I think step 1 actually is not as simple as that. Getting open sometimes requires help too. Does a pick worth anything? It certainly does. I'd like to see the NBA start to record successful picks that result in made baskets. That will show the effort of some players whose stat numbers aren't as good as they are actually worth.

    Until decent play-by-play charts appear via some resource (nba.com say) it will be hard to figure out things like "setting a good pick"...

    But the point is well taken. The "normal" stats can show you something about individual offense and can give you a feel for team defense but its not very precise.

    Are you sure? Would you trade 10 less points a game for 1 less turnover?

    That's the equation that the stat comparison suggests...

    ER *can* factor in minutes played. A version of ER goes like this:

    ( Points + rebounds + assists + steals + blocked shots - missed field goals - missed free throws - turnovers ) / ( minutes / 48 ) = ER per 48 minutes.

    This also is an "official" nba.com stat.

    A player with a game ER of 30 (All-Star range, what Hakeem would average per season in his prime) often has a per 48 minute ER of about 40 or so. So while 15 ER is average and 30 is really great, it seems that ER/48 mins, 40 is great and maybe 20 is average.

    And yes, ER does tell us that Steve is doing the work of 2 regular players.

    I didn't say earlier but I looked at this link for a while. Cool stuff.

    I'm calling the equation an Efficiency Rating cause people can then look it up on NBA.com and see that I'm not pulling my numbers from thin air.

    Dean's Site seems to poop out sometime in the late 1990s. Anyone know if he is active somewhere else now?

    The turnover vs. missed shot is kind of interesting. I wonder if there's a stat that shows how likely a team is to score off a turnover than a missed shot. Missed shots almost always allow a team to get back on defense quickly. But a turnover often results in fast breaks.

    John Hollinger, who made the argument, figures, on a seasonal basis, that a proportion of team total assists should be subtracted from a player's points scored to factor in what assists have done for a player's scoring average.

    It's an approximation, to be sure.

    Game 6 Efficiency Ratings...

    Ranked by per 48 minute efficiency...

    S Francis: 30.0 per game; 36.15 per 48 minutes
    K Cato: 16.6 per game; 28.46 per 48 minutes
    K Thomas: 11.5 per game; 20.63 per 48 minutes
    E Griffin: 13.7 per game; 19.68 per 48 minutes
    C Mobley: 14.8 per game; 16.56 per 48 minutes
    ---------------------------------------------------------------
    Y Ming: 4.5 per game; 15.2 per 48 minutes
    J Hawkins: 7.3 per game; 13.9 per 48 minutes
    J Collier: 3.0 per game; 12.0 per 48 minutes
    M Norris: 5.3 per game; 11.9 per 48 minutes
    B Nachbar: 2.0 per game; 8.0 per 48 minutes
    G Rice: 1.0 per game; 2.53 per 48 minutes
    M Taylor: -2.0 per game; -7.38 per 48 minutes


    Ming's ER took a big jump because of the Portland game, from something in the lower half of the reserves to now, the best per minute performance of the reserves. Ming's efficiency rating in the Portland game was 12 in 15 minutes, which factors into an All-Star 38.4 computed on 48 minute terms...

    Which sort of shows it's a bit premature to celebrate or denigrate any of these guys yet. Cato's prolly had super numbers last year, too, *when* they pass him the ball, he usually right next to the basket and if he doesn't fumble it, it's a pretty good scoring opportunity.
