Delay on the Defense?

[RoyGardner]

We had some discussion related to this during a junior college scrimmage (NCAA rules) Friday night. While B is clearly entitled to a reasonable delay to substitute in response to A's substitutions, if A's 11 players are already on the field and in their huddle, ready to go, then IMO B is causing the delay.

We discussed keeping the U over the ball until B is lined up while keeping an eye on the 25 second clock (not allowing A to snap if B is not lined up). If the 25 second clock gets down to 5 or less seconds, then blow & throw and charge B with DOG.
