Snap/Dead ball fouls

[Texas Aggie]

are fouls that are simoultaneous with the snap dead ball fouls?

NCAA: some are and some aren't. The ones that aren't (like illegal motion and illegal shift) are not always simultaneous with the snap but could be.

When in doubt -- when its on the offense -- shut it down. That's how we do it, anyway. The last thing I want to do is bring back a TD and most coaches aren't going to know which fouls are dead balls and which ones are live. I'll deal with the ones that do by saying something like, "Coach, if we missed that play (as far as not letting it happen) there wasn't any harm to your team absent your total speculation on what might have happened -- plus, nobody got hurt since we killed it." He's going to concede the latter point.
