PSK or not? - NCAA

[With_Two_Flakes]

OK, I'm no rules expert, but I'll take a stab at it.

The fumble into the pylon gives a Touchback to A. Since B didn't end the down with the ball, it can't be PSK as that is one of the five requirements for PSK.
If A accept the penalty, the illegal touching dissapears.
Since it isn't PSK, the penalty is administered from the previous spot.
1/10 for A at B's 33.
