#11 is very troubling.
Scenario: Texas 24, Alabama 20. All T/O's exhausted (both teams). 0:18, 4th period. Tide, 2/10, on the Horns 30. Tide all-world QB is flushed from the pocket and advances to the B-25. As he is going down, his helmet comes off (no foul). 0:09 on the game clock when the officials stop the clock for the apparernt helmet-comes-off. Holy crap. Star QB will have to sit out 3rd down. Assistant coach for Tide yells at right guard, "Go down! Go Down!" Right guard obediently falls to the ground in "obvious" agony. No one on the crew sees the RG flop, so they have no choice but to assume he was hurt during the play (not sure that matters, though). By "interpretation," the right guard goes out for a play (per the injury rule), but star QB stays in the game. with no 10-second subtraction. QB throws a TD pass on the next play, and Mack Brown gets fired for losing to an SEC team.
All you SEC folks say 'yea.' All you B12 folks say 'boo.' That ain't the point. It could be anybody, but such a scenario would raise a stink, eh?
