When seeing the technique initially, I had two thoughts on possibly why they use it.I don't doubt that; it seems like a more difficult technique to teach a new center rather than the tried and true method.
a) It allows the center to be more upright (head higher) while still having the ball touch the ground. This allows him to see the field better to do line calls and be higher allowing him to move quicker to start blocking.
and
b) I'm guessing the QB's like how the ball is delivered to them.
And....I'm also guessing that teams have seen little to no negative affect with the change as far as accuracy of the snap.
