http://sports.espn.go.com/nfl/news/story?id=2389062 Here's a list of the ones that did pass: - Limited celebration - Replay changes - A rushing defensive player won't be allowed to forcibly hit a quarterback below the knees. - Centers who snap on field goals, extra points and punts can not have a defender line up directly over him. - Expanded the definition of a horse collar tackle. - Other little changes for safety included trying to limit the number of re-kicks by giving the kicking team more chances to take penalties after kicks. - The owners also prohibited kicking teams from loading up one side of the field on free kicks. - In a vote of 29-3, owners allowed teams to keep 75 instead of 65 players on their roster in the first cutdown, which is annually the Tuesday after the third preseason weekend. The trade off was the NFL Europe exemptions that allowed teams to bring more players to camp expire at that time. Ã¢â‚¬Â¢ The Bucs' recommendation to include all penalties for replay review was almost unanimously defeated. Ã¢â‚¬Â¢ The Chiefs proposal to expand the playoffs from 12 to 14 was tabled to May, but it doesn't have the support of Tagliabue and the Committee and is expected to fail. The Committee also completed a six-page clarification of the writing of the holding penalties that it hopes will bring uniformity to the calls and the coaching of offensive linemen.
