Unsportsmanlike Conduct

[aschramm]

First year official here, 8th game in:
Just finished a 3 game set of youth games as a HL, and during one we had an unsportsmanlike conduct call (player from team A was high-stepping into the endzone). Is this considered to be a live or dead ball foul, and does this affect the spot for the next play? Our Referee declared it a live ball foul (I believe, there are alot of calls going through my head that will probably get posted later), and enforced the penalty on the try after.

Also as a side note, I know we aren't supposed to be complete sportsmanship police out there, but team A had a 35+ pt lead with about a minute to go, and just kept running the ball instead of taking a few knees and ending it. Team B coaches on my sideline weren't too happy at all.
