I can see how one would think this is a possibility. I even thought this might be the case as well. But earlier in the game the kicker was kicking the ball down field very consistently. The kicker was also making extra points with little to no trouble. As we all know, even a bad squib kick is typically going to at least make it to the second level of the return team. These two kicks were directly at the first level of the return team and obviously kicked to not go more than 10 yards. The negative reaction that was easily heard from many of the Ryle fans of the onside kicks was even obvious. Like I said, different teams have different approaches...
On a side note, Ryle does probably have one of the best kickers I have seen at the freshman level this year.
