I could care less one way or the other, but to me, I think the rulebook is clear. I've always been taught, and I teach, not to read past the words on the page. If they meant 'at the snap', then they would have printed 'at the snap'. The only reason a holder, with his knee on the ground, would be allowed this exception is for a kick and no other reason. Next thing you know, there will be all these exceptions to a runner having his knee down and people crying that 'he could have made a kick!!!' (ok..small bridge I just jumped off there...but anyway)
To me, this debate will be settled next year when the book is printed....if the language is different, then what we just experienced is a rule change...if the language is the same, then a rules interpretation.
