This happened in last night's Cal/Texas game, but I assume it was not planned. But maybe it should be considered in the future as a planned strategy? To wit: when an onside kick is delivered and it is angling to out-of-bounds with decent speed, would be if safer for the receiving team to try to fall on it, OR to instead set up a line of blockers between the ball's trajectory and the kicking team, and simply let the ball continue out-of-bounds, negating the possibility of it being punched loose from a receiver?

Can that strategy be relied on? If an onside kick is done right, it can do all sorts of strange things other than just go in a straight line. Most onside kicks are attempted to try to get the ball to die before it reaches the sideline.

Usually on hands team the front guys will run at the kicking team to give the guys in the back time to catch the ball cleanly. Not every guys job is to recover the ball.
