Watching the last few kings games has made me understand completely that cousins has a right to be pissed off, even if he is too immature to express it correctly. Back in the day the way a big man would handle this situation is to tell his guards that he is going to get post position and not move, and it's up to them to get him the ball or get an offensive 3 second. Don't think the media would be favorable to something like that these days, especially from someone with his reputation.
It's not like he wants to be known as the least efficient big man in the league, and this offense doesn't play to his (or anyone on the team really) strengths at all. He always gets the ball on the elbow and is expected to find cutters, only there are no cutters cause no one on this team knows how to move without the ball or utilize a screen.
They'll spend 15 seconds running the most useless ineffectual pick and rolls then dump the ball into cousins in the high post or 10 feet outside the low block with 5 seconds left on the clock and expect him to bail them out.
None of this excuses him shooting like 10% on offensive putbacks at the rim though. I think he is taking the 'don't bring the ball back down on an offensive rebound, just tip it in' big man coaching mantra too seriously. Sometimes you need to grab it with 2 hands and go up strong if you don't have the angle for an accurate tip, you'll at least force a foul, and he is hitting his FTs well this season, so he doesn't need to worry about going to the line.
