It appears that I'm taking the minority opinion on this
....
When we added the spiking exception back in 1995 a major concern was if this would become a second choice after the QB deemed that all his receivers were covered. Allowing it only on a hand-to-hand snap appeared to reduce that possibility. Since then expanding the spike to the shotgun formation has came up several times including a couple for a final vote. While it is allowable in NCAA, it received a support setback this past year when it was learned the NFL has the same rule as we currently have.
Several times the "tackle box" rule has also appeared. IMHO, to allow a scrambling QB that is about to be sacked to dump the ball, is penalizing the defense.
IMHO, one of our jobs is promote an even balance between the offense and defense.
IMHO, one of the jobs at higher levels is to sell plenty of tickets and TV exposure. High-powered offense does that.
IMHO, spiking the ball = wanting to stop the clock = if done from shotgun = intentional grounding.
IMHO, these are only the opinions of a nervous ole' zebra worrying if the Red Sox (starting @ 4 EDT) will be over before the Patriots (starting @ 8 EDT).
