Typical Chiefs. Their corners could not cover their own cocks with a sock, so they want the PI rules changed to enable them to get away with more. The rule change wouldn't hamper their offense nearly as much as many other team's offenses, since the queef wideouts suck and so rarely draw flags anyways.
Having said that I did not agree with the decison to 're-emphasize' the illegal chuck rule in the first place, anymore than I agreed with the original decision to limit the chuck to 5 yards rather than 10. I do agree with Bill Bellichick that the league's competition committee should never again be allowed to make such a change in terms of telling officials to be all over a rule like flies on ****, without a prior vote of the team's owners. Bellichick has put such a motion before the NFL meeting.
