Question:
Center snaps ball and immediately cuts down on the nose guard. Let me explain the block: Just as he snaps the ball, he goes down to the legs and ankles of the nose guard.
Is this legal?

Here is something I put together for blocking. I hope the formatting works as I have it in word.
Blocking, free blocking zones, illegal blocks
Clipping Initial contact at or below the waist against a player other a runner or pretending to be a runner.
Clipping is permitted in the FBZ when
1)by offensive linemen on the LOS and in zone at snap
2)against defensive linemen on LOS and in zone at the snap
3)the contact is in the zone
4)the ball is still in the zone
Summary: Only offense can legally clip. All must be on LOS and in zone at snap.
Blocking below the waist - initial contact at or below the waist from the front or side and they are not the runner.
BBW is permitted in the FBZ when
1)by all players who are on the LOS and in the zone at the snap
2)the contact is in the zone
3)the ball is still in the zone
Summary: Anyone who is on the LOS and in the zone can BBW.
Blocking in the back initial contact is in the opponents back, inside the shoulders, below the helmet, and above the waist, and against a player other than a runner or pretended runner.
BIB is permitted in the FBZ when
1) by offensive linemen who are on the LOS and in the zone at the snap
2) against defensive players who are in the zone at the snap
3) the contact is in the zone
4) the ball is still in the zone
Summary: Only offense can legally BIB. Offense must be on LOS and in zone at snap, defense just in zone at the snap. (LBs are probably in the zone at the snap)
Butt block Illegal using the facemask, front, or top of helmet to make contact at any time.
Chop block Illegal delayed block at the knees or below against an opponent who is already engaged.
1st block high and 2nd block low illegal, 1st block low, 2nd block low illegal
Key only illegal if the 2nd block is low.
All simultaneous blocks by 2 on 1 defender are legal!!!
