Newsflash… If the other team has a great returner, kick the ball in the damn end zone and he won’t be able to return it. Oh, instead kick it short to the 10 yard line and they run it past the 25 we hurt ourselves. If we make the tackle inside the 25 yard line, it is beneficial. That is why I still would maintain. There should be a metric that the staff can look at to determine whether or not their short kick results has been effective.
In theory the advantage of a high kickoff that comes down at about the 10 is that a team isn't going to get a long return on a very high kick, so the receiving team may start inside the 25. They removed that strategy, however, via a rules change. Now, a team can fair catch it at the 10, and they get the ball at the 25. Thus, there is no longer any reason to kick balls very high. Just kick the ball in the endzone, or kick a hard, low, line drive, and aim it for someoene's head. ;)
