Maybe I don't understand it, but is he saying our starters would, per 40 minutes played, average 94 points on their own?
Yup. And if they all played 40 minutes a game, that sounds within reason. That would only leave 8 minutes per game at each position for reserves. They won't all play 40 minutes a game, though.
For Oden, 18.6 might be a little low depending if he Roy can begin to learn to run the offense through him. But assuming the same 16.7/per36, that translates to 18.6 (probably more like 14-15ppg). The 13.0 reb is accounting for Camby having some shared minutes with Greg out there and causing some diminishing returns on his 12.8 reb/per36 (which comes out to more like 14 reb/per40). Still think he'll be around 10-11 rpg.
HCP's head just might explode when he sees this thread. You know how much he loves Per-40/PER numbers.
Pelton is higher than Hollinger in assists for all 5 players, and lower in rebounds for practically all 5. So they either disagree on team totals, or on what the substitutes will get.
