this will sound like one of those contrived law quiz questions but genuinely happened to me yesterday.
Red are leading 36 - 29 when Blue score a try right on full time so 36 - 34.
Blue take conversion, chargers yell out and conversion misses.
So I order a retake - so far so good.
Blue decide to change kickers. Red bench goes ape-shit "has to be same kicker!", etc
I allow new kicker who, of course, successfully takes conversion. FT: 36 all draw.
Red team less than happy.
So 2 questions:
1. was I right, in law, to allow a change to kicker?, and
2. even if I was right, have I made the final score about myself and would it have been better management to enforce the same kicker?
