And as Wagner noted after the game, some are lower than others: The crouched position of the snapper leaves him low. So how do you beat a formation that looks like this? The defense can hit the snapper, but the rule gives him time to adjust out of the incredibly vulnerable snapping position. The NFL has different rules, but the defense is not allowed to line up within a yard of the line of scrimmage between the snapper’s shoulder pads. In college, roughing the snapper is a foul, just like roughing the kicker or passer. Since long snappers are crouched over and looking through their legs at the snap, they are completely defenseless, and hits would result in serious neck and back injuries. The easy thing, then, would be to bulldoze the long snapper. They get the worst ratings in the game, which led to this fantastic piece of Early Sports Internet Humor. Instead, the long snappers are graded on their agility and blocking. The game just makes long snapping automatic, because nobody wants to lose to their friend on a bad snap.

Mulase, Motohico (1979), "Poles of instantons and jumping lines of algebraic vector bundles on P³", Japan Academy.Then a plane of V corresponds to a jumping line of this vector bundle if and only if it is isotropic for the skew-symmetric form. There is a rank 2 vector bundle over the 3-dimensional complex projective space associated to V, that assigns to each line L of V the 2-dimensional vector space L ⊥/ L. Suppose that V is a 4-dimensional complex vector space with a non-degenerate skew-symmetric form. If the bundle is generically trivial along lines, then the Jumping lines are precisely the lines such that the restriction is nontrivial.
Lines such that the decomposition differs from this generic type are called 'Jumping Lines'. Given a bundle on C P n, with decomposition of the same type. Still one can gain information of this type by using the following method. This phenomenon cannot be generalized to higher dimensional projective spaces, namely, one cannot decompose an arbitrary bundle in terms of a Whitney sum of powers of the Tautological bundle, or in fact of line bundles in general. The Birkhoff–Grothendieck theorem classifies the n-dimensional vector bundles over a projective line as corresponding to unordered n-tuples of integers. The jumping lines of a vector bundle form a proper closed subset of the Grassmannian of all lines of projective space. In mathematics, a jumping line or exceptional line of a vector bundle over projective space is a projective line in projective space where the vector bundle has exceptional behavior, in other words the structure of its restriction to the line "jumps".
