Passcatcher allowed a step?

[Jurassic Referee]

Yo, Duketownie, here's the applicable NFHS case play- 10.6.3SitD:

A1 is running towards A's goal but is looking back to receive a pass. B1 takes a position in the path of A1 while A1 is 10 feet away from B1. (a)A1 runs into B1 before receiving the ball; or(b)A1 receives the ball and before taking a step contacts B1.
RULING: In both (a) and (b), A1 is responsible for contact. In (a), B1's position is legal if A1 has been given two strides prior to contact. In (b), since the position of B1 is legal when A1 has the ball, the contact is charging by A1.

NCAA uses the same concepts.The idea is to award good defense.

Btw, from an official's standpoint, Coach K is a whiny jerk.He oughta get the Jim Boheim Lifetime Achievement Award for Whiny Jerkism.
