This team has 8 walkons, including the starting SF. Looks like the SIM has it set to play the 4 scholarship players practically the entire game, though only this center Haney that's grabbing all the boards has legit stamina (95) to do so. The PF with similar ATH and REB ratings has only 62 ST, so he's winded probably half his playing time, making him pretty useless grabbing a board apparently (4.7 rpg) but somehow still good enough to be second on the team in scoring while shooting 45% on FGA. That part doesn't jive with me. The monster center is playing 39 mpg, while the PF is hauling in 31 mpg....all the while playing the FB offense. Nice!
But, ironically or coincidentally, it was OR who just a couple of days ago in another thread said he knew how to get a kid to average 15 rpg....just have horrible rebounders on a team except for 1 kid and that kid will grab most of the boards. I think this team fits the description to a T. Also, I think someone else said the engine favors rebounding from the center position over the PF position, so that's contributing here as well I'm sure.
