Sadly that's not just ABC. Two of the things that drive me nuts in the NFL is how hard the refs try not to call intentional ground or safeties. If they can find any sorry excuse why a throw as actually a "pass" or why they shouldn't spot the ball in the wrong endzone they will. And extra good luck trying to get an intentional grounding call in the endzone, the refs have many volumes of excuses against that call.
One other thing that could be improved is to alter the rules so that there are more punt returns. The punt returns are some of the most exciting plays in a football game. Too often they have to call for a fair catch, and often the ball is kicked into the end zones or out of bounds. Efforts should be made, imo, to increase the number of punt returns by altering a rule or two. It would be easy.
