It should be pretty easy to argue a downgrade, plainly DWZ was going for a tackle to wrap up the ball with his right arm. Cleary tried to palm him off with his left hand on DWZ shoulder, this forced up DWZ arm. Also Cleary ducked such that his head lined up with DWZ arm. This image plainly shows it, look at where DWZ's palm is facing, downwards toward the ball. Look at where Cleary's left hand is, on DWZ's shoulder, then look at how much effort he is exerting as shown by his bicep muscle, obviously an attempt at a palm off. Lastly look at how much Cleary is crouching, he was plainly trying to slip under the ball and all tackle and at the same time pushing DWZ shoulder to move his arm upwards to more easily get under the tackle.
The tackle plainly shouldn't even be graded as Grade 1 Careless since it was Cleary who moved the tackling arm upwards whilst at the same time he ducked into it.
