If i remember correctly, the one you refer to as the first one, the ball was in the air... and the ball being in the air negates the 5 yard bump being legal. Once the ball is in the air, you cannot make any contact with the receiver.
Now if you had thrown Steve Smith's TD out as a bad NO-CALL i would agree with you because he pushed off and elevated...
On the second one, i do remember the ball being a long way from catchable, and that call i agree with you on, but none the less, he shouldnt have left it up to the official. If he gets his head around he see's that the ball isnt catchable, and he not longer engages Smith, and were not having this conversation today.
