The first full weekend of exhibition games featuring the new dynamic kickoff included two long returns, a significant drop in touchbacks and mass confusion on an odd play that ended up as a rare safety.
The NFL's goals of increasing the rate of returns and bringing back the threat of big plays were mostly accomplished last weekend. The NFL reported 81% of kicks have been returned so far this preseason, even if teams have been a bit guarded in what wrinkles they were willing to show before the start of the regular season.
''You've seen everybody pretty much be vanilla in the preseason with the kickoff and how they're attacking on kickoff return,'' Raiders coach Antonio Pierce said. "I think the key part for us is seeing our guys run down and cover and who can make the space tackles.''
It also was important for everyone to understand the new rules, as evidenced by what happened to the Kansas City Chiefs when they tried to down a ball for a touchback only to have it be ruled as a safety.
The play in question came late in the first half of Kansas City's game at Jacksonville on Saturday when Cam Little's kick for Jacksonville landed in the front of the end zone before bouncing back into the field of play.
Mecole Hardman raced back and kneeled in the end zone before picking up the ball around the 1 and bringing it back over the goal line. Under the old rules, a kickoff that landed in the end zone led to a automatic touchback.
The officials on the field initially ruled the play a touchback but because it was in the final 2 minutes of the first half, it was automatically reviewed. The call was then changed to a safety because Hardman brought the ball from the field of play into his end zone.
''I think it's a good coaching point for all teams, to really coach our returners in that situation,'' Jaguars coach Doug Pederson said. ''It's definitely going to be on the coach's video that's going to come out this week. It's really a good teaching moment for everybody, us included, for our returners. It's just a great way to learn that rule and to learn the game of football.''
