Man, talk about asinine use of statistics. This is not even remotely suggestive, let alone relevant.
First rebounds... Since the Sonics obviously outrebounded the Kings, of course Ray + Rashard's 9 boards are a smaller percentage. But by any one's math, 9 > 7. It doesn't even make sense to look at percentage of teammates' rebounds. Common sense says grabbing 9 boards required 2 more "movement to the ball" efforts than 7 boards.
Assists and Steals... I look at these and it seems to me of all the court activities, these are among the least likely to get you winded. I mean jump shots, layups, drives, blocks, rebounding, etc. I can understand. But passing and stripping? Seems more like attentiveness to me. Bibby probably expended more effort on his assists cause he sometimes drives and dishes. Also, with steals, you realize if Ray or Rashard gets 1 more steal, they'll be at 3 of 5 or 60% (10 percent points based off 1 steal, hahahah)? When you got numbers as small as that, using percentages is just too ludicrous. Steals and Blocks only become statistically relevant over many games. Heck, shooting isn't even statistically relevant for any one game unless we're talking about a volume shooter (a scrub going 3/4 is 75%, but common sense dictates that doesn't mean he can go 9/12 with more attempts).
Just another example of horrible application of statistics, IMO ( and to prove tiredness of all things? ). I don't even understand what one's relative production to his teammates has to do with anything. This would mean if your teammates are more productive, you must be fresher. And if they suck, you get more tired (you may be dispirited, but physically tired? c'mon...).
Bottomline, whether or not Bibby and Peja were more tired, I assert that isn't an excuse. Hell, Bibby has come out clutch in OT performances playing close to or over 50 minutes. So have many stars and superstars. Ray and Rashard, even if they weren't as fatigued in this particular game, probably had numerous games where they played through it. And even using absurd math, does the difference really look that big where one side is obviously more tired than the other? You know what's the most relevant stat missing? Minutes. The rest is conjecture based off incorrect application of stats any college professor would cringe at. This ignores the best indicator as well: watching the game.
This is not to say one player can't be more tired than another playing the same number of minutes. But there are much better examples like say in the Dallas vs. Houston series where T-Mac has to guard Dirk but Dirk guards someone like Scott Padgett on the other end. Then there's conditioning, but you assume that most NBA players are well enough conditioned where it's a wash (Ostertag definitely not being in that group).
