Setting a screen IS an offense and it DOES force Dickinson to defend. By the end of the game, Dickinson was exhausted from having to defend screens. It was the timely late 3s that beat us, not Dickinson's interior skill on either end.
Clingan can't post up effectively against a 7'2 beast of a man. He's not that good yet. His feet aren't coordinated enough unless he has exactly the right spacing, and he has meatloaf hands. You screen and roll hard and get Clingan the ball moving towards the hoop or give him an off-ball screen to get him to his strong hand. This worked twice with Clingan and once with Johnson IIRC.
This is exactly what the NBA wants from Clingan anyway. I doubt he spent last summer learning to post up like Sanogo. If he wants a paycheck, he needs to defend like a madman, rebound, be excellent in the screen and roll, and show some propensity for shooting from distance.
Dickinson is a darn good defender and with limited spacing last night because our shooting was so off, we didn't get as many opportunities as we would like putting Clingan in those positions he's comfortable in. It's unlikely we face a 5 as big, strong, and talented as him again unless we play Edey.
What we CAN'T have Clingan doing is banging for position in the low-post and making a post-move with 1-2-3 fakes to get a tough layup in. He's not Sanogo, and that's simply not part of Clingan's arsenal. We need to find him for a quick catch and turn or 1-dribble for a dunk, lay-in, or up and under. Otherwise, kick to it to a shooter. The longer he has the ball, the worse he looks.
