The call itself could be up for debate. He was definitely moving, so a block call is fine. The issue is how it was overturned. They called a charge and he was very clearly out of the restricted area. The refs can only go to review if they think he was in the restricted area, they went to review when it wasn't needed. Once you are at the review, the refs then can determine if the foul call was right and keep it or overturn it. This only applies to the 4th Quarter and last two minutes. There was no reason for them to review in the first place because he was out of the restricted area. It was just weird.
