should I have thrown a flag??

Kickoffs are tough, in that you are encouraged to only call holding penalties when they affect the play ... but on a kickoff you'll never know which holdings may eventually affect the play. At SubV, I'd have probably let it go and informed the coach of the offending side to tell the kid to knock it off (and perhaps flag the 2nd one on the same kid). But at Varsity, they know better - flag it.

Worst thing would be if you didn't flag it, the kid that got held may do exactly the same thing later (or the offender even, thinking it was not going to be called), but be nearer the ball and get flagged - not exactly fair, and confusing to the kids.
