A&M Bama game. 4th and 6, A&M (Team A) punts. Bama (Team B) runs player 12 on the field right at the snap and he stays on. Deep flank flags it -- play continues as punt, which Bama downs or gets tackled around their own 10. They call illegal sub and enforce from the Bama 10 (succ. spot), first and 10.
The live ball illegal sub foul clearly says previous spot for enforcement. One buddy I talked to said he thought it was PSK; he called our chapter rules guy who said they got it right (don't know if he thought PSK as well). If that's true, what am I missing? If they went with dead ball illegal sub, the play should have never happened, so the succeeding spot would have been where 4th and 6 was. Plus, I thought PSK was only if there was no specified enforcement (i.e. basic spot).
