First on the "slam" it was not even close, he jumped up, left his feet and they both fell uncontrolled back to the mat. It is no different than a guy who puts in both legs and the bottom guy stands up and just jumps backwards, no way they are landing "under control". He landed directly with one shoulder into the stomach as well, it was intentional. There is no way to land under control the way they left the ground.
On the takedown I completely agree with the call and the for the above mentioned reasons. There has to be control "beyond reaction time". Also the whizzer was there when the call was made, you must provide the wrestler the opportunity to defend himself "beyond reaction time".
I'm sure I'm just an average official so I'm probably only 1/2 right in this situation.
