I, too, was wondering if it needed to be a foul for a free kick out of bounds to NOT be a foul for an illegal wedge, and asked that question on the NCAA forum. Former Big 10 Referee Bill Lemonnier offered his opinion that, no it does not require a free kick out of bounds foul for a wedge to NOT be a foul. If it is any kind of free kick out of bounds, touched or untouched by either team then no foul for an illegal wedge. You could still have the illegal kick out of bounds foul, just not a wedge foul. Lemonnier is not the official rules interpreter or the Sec-Ed, but he's a whole lot closer to those folks - even today - than I ever was. Good enough for me, for now.
