Improper equipment

[Zeke5]

db,

I'm assuming that you reference to "Team A" is actually
"R" on a scrimmage kick.

I'd have to agree with BillC's penalty and assessment
facts, but I'd need more info on the situation in which
this player unhooked his chinstrap before I'd dart him.

1. Was this something he or another teammate was doing
throughout the game and was warned?

2. Was the player a safe distance from the action of the
runback, or from a K player looking for a cheap shot, or
was the player making no attempt to further participate
in the play?

Even though there would not be a coach out there who could
refute this call, this would be a rather "ticky tack" call
especially if it brought back a long return by R.

If the player's safety was not at issue, the player would
have to unhook his chinstrap in an egregious
unsportsmanlike manor (or remove his helmet) before I'd
ring him up for the 5 yarder.

That's just my $.02. Interesting play nonetheless.
