We\'ve all heard that \"noise\" (that\'s the right word for it).
Teams have to somewhat adjust to that rule, so it\'s a good idea to have NFL refs come in and show the CBs exactly what they will tolerate and what will earn a penalty. Defensive backs coaches will have a close eye on pre-season games and how the rule is enforced there.
I\'m not sure that the rule itself will have a big impact - maybe that CBs will play less aggressively, give a cushion and don\'t bump the receiver at all on more plays this year. What I wouldn\'t want is for the pass interference rule to be affected as well. It\'s scewed enough as it is, I don\'t want every involuntary tangle leading to a new first down.
