Does this play meet all PSK requirements?
No, it wouldn't, since Team A is in legal possession at the end of the down. The penalty statement says that such a foul on a scrimmage play is PSK enforcement. However, I believe that this presumes Team B is in possession at the end of the down. Otherwise, Team A would decline the penalty, and enforcement would be moot.
Somebody can probably dream up a scenario in which Team A would want to accept the penalty, but I'm not gonna wrack my brian on that one. But, if they did, it would be a previous spot enforcement.
