No need to get defensive with your snide comments. It's partly your fault for asking for help and not even providing enough information. If we were mind-readers, the world would be a much safer place.
Anyway, if you're playing low post, then IS would be your most important offensive stat, so player 2 looks like the better choice. If his GS is better, then that should help improve his ID. As for rebounding, it's entirely dependent on what defense you're playing, which of course, you haven't mentioned. Man to Man should provide you with standard rebounding, but play 3-2 zone and your rebounding should, theoretically, be less.
