Kidd was fined $50. The Nets were out of time outs and he was trying to kill the clock so he could set up for the last play. His was obvious and he should be fined. The Nets lost anyway.
Tomlin's is different. He did impede/alter the Ravens player; however, I don't think there was any intent on his part to do that. (although his smirk at the end may say otherwise). I do think he will also be find but it will lower ($25K?).
