Roughing the Kicker

[bossman72]

These are kinda tough to describe but I'll try my best.

1) FG. A defensive player comes off the edge and misses blocking the kick and roughs the kicker. However, the kick is blocked at the line of scrimmage by a lineman. Does this negate the roughing the same as if the person off the edge blocks the kick himself?

2) FG. A defensive player is coming off of each edge of the formation. The player off the right edge dives to block the kick, but misses and roughs the kicker. The player off the left edge is almost immediately in front of the player coming off the right edge and blocks the kick. Does the proximity of the kick being blocked in relation to the kicker/holder matter?
