Combinred performance at each position for the Rockets.

All too often do I hear people complain about Rudy subbing players out that are potentially having a big game that night but get subbed out for a quarter for another player to get some time on the court. I'm not going to argue about whether what Rudy does it right or wrong, but I simply want to ask what each player that plays PG,SG,SF,PF, & C what combined performance they get out of eachother. For example.

Say Ming score 15 points and grab 11 boards in one game, and Cato in the same game get 6 points and 8 in a short period time, then the combined performance at the Center position would be...

21 Points, and 19. Now this may sound like I'm backing Rudy when he subs in new players, but collectively at the Center position I think those numbers are terrific. I mean if Cato and Yao can do that tonight against Shaq, we'll definitely have a shot at a win tonight.

Anyhow I was just wondering if there was a stat around that combined each player and the position they play, and combined their stats with other players that play the same position.

I only ask because I really want to see if Rudy's subbings statistically are efficient or not compared to the other Centers in the NBA, the other Power Forwards in the NBA, other Small Forwards, Shooting Guards, and Point Guards.

I think it could also help boil down what our weaknesses are at each position easier, and whether it is in fact coaching or having a weak bench of guards,forwards,centers that don't contribute enough. If there is a stat or a site that covers that, I'd like to get a look at it. If it also includes minutes played, that's terrific too.

While stats don't always tell the whole side of the story in a game, they do give a good indication of how well each position is played.
