See above for an explanation for Crosby having his highest career kickoff average. I already posted that some weeks ago but as it happens with most things that support the notion he struggles it got ignored.
-----------------------
I don't think this issue has been ignored. I believe there were other points that took precedence, so it was pushed onto the back burner.
I believe the new kickoff rule makes for an interesting topic. With the ball coming out to the 25 yard-line, it changes the dynamics of the game tremendously.
Instead of going into the nuts and bolts of it, we all know penalties and injuries happen quite often on returned kicks. Those penalties often create a long field for the team going on offense. A shorter field is preferred. As for the defense on them, the injury issue comes into play, and the non-returned kick cannot be run the length of the field for a TD.
If I was an NFL head coach, I would say that we don't want kicks returned if they reach the end zone. Play with that intent. If we have to return a kick, do so, but otherwise no. I like the ball on the 25, because it's a shorter field than what often happens when we try returns.
As a kicking team, I'm still in favor of sticking the ball in the end zone without a return, for the same reasons except there's no threat of the ball getting outside the 25 to start their drive. Of course, if I have a coverage team that is lights out, I might want to see the opposition try returning the ball, so we can nail them inside the 20.
A stat that I would research, if I had the time, or the access, is the success rate on drives that result from touch backs versus those that are kicked shorter. I wonder if there's data that compares turn overs inside your own territory on ensuing drives, average field position achieved, and comparison of scoring TDs and FGs as well. Also, the amount of clock you control for them in comparison, along with first downs.
These are all those second level statistics that I'd bet someone at STATS has worked out. They've got some keen analytics.
