NCAA philosophy on Too Many Men in The Huddle

[JugglingReferee]

Does such an animal exist?

If so, what is the though governing calling this foul/not calling?

[NVFOA_Ump]

The associated AR is very specific as to what the philosophy is:

SECTION 5. Substitutions / Legal Substitutions—ARTICLE 2 / Approved Ruling 3-5-2

III. A33, an incoming substitute, enters the huddle or assumes a position in a formation and (a) after approximately two seconds, A34 leaves the huddle and departs the field of play at his sideline, or (b) after approximately four seconds, A34 leaves the huddle and departs the field of play at his sideline. RULING: (a) Legal. (b) Foul. (Note: A departing player who leaves the huddle or his position within three seconds is considered to have left immediately.)

[SMATX]

One point to remember is the definition of a 'huddle'.  Until the Referee makes the ball ready for play it is impossible to have 'too many in the huddle'.

RULE 2   SECTION 13. Huddle
A huddle is two or more players grouped together after the ball is ready for
play and before a snap or a free kick.

SECTION 5. Substitutions / Legal Substitutions—ARTICLE 2 / Approved Ruling 3-5-2

III. A33, an incoming substitute, enters the huddle or assumes a position in a formation and (a) after approximately two seconds, A34 leaves the huddle and departs the field of play at his sideline, or (b) after approximately four seconds, A34 leaves the huddle and departs the field of play at his sideline. RULING: (a) Legal. (b) Foul. (Note: A departing player who leaves the huddle or his position within three seconds is considered to have left immediately.)

In additon, Team A can not break their huddle with 12 of more players.  This is a dead-ball foul even in scenario (a) above if the huddle broke simultaneous with A34 beginning his departure.

Also, this restriction does not apply to Team B.

[NVFOA_Ump]

Also, this restriction does not apply to Team B.

Do agree that the specific language "breaking the huddle" refers to Team A, but the rules apply the three second requirement equally to both Team A and Team B.  See rule 3.5.2.c and note the following AR:

Rule 9 / SECTION 2. Unsportsmanlike Conduct Fouls / Unfair Tactics—ARTICLE 2 / Approved Ruling 9-2-2

IV. Between scrimmage downs, one or more Team B substitutes enter the field of play. Before the snap for the next down, more than 11 Team B players intentionally stay on the field of play as long as possible (more than three seconds) to disguise the defensive personnel, the type of defense and the pass coverage. RULING: Dead-ball foul on Team B, illegal substitution. Penalty—Five yards from the succeeding spot (Rule 3-5-2-c).
