Seems to me there are certain times or situations that unless the offender uses an ax, no penalty will be called because no ref wants to be focal point of that kind of controversy. The hold is probably an example. I kept holding my breath after Austin hit the EZ, waiting for a penalty flag back upfield. A clip, hold, offside, block in the back, too much white, whatever. But probably it would have taken a street mugging to get it called. Were I an official nothing would get flagged then. Let 'em play.
