I thought so too and that was my argument at the time, but if you manage to find the old thread - you will find that I got a right virtual kicking. :biggrin:
I'm pretty sure the incident I commented on was an England Veterans game at Twickenham; and I'm almost certain the Hooker ran virtually the length of the field to score while being "supported" by a team mate.
I recall a previous debate where the support player did not move at least three times (as in this case) so I don’t think the cases/examples are comparable, hence you can get a different result.
in this case it is clear obstruction. The support player has deliberately changed lines on several occasions to obstruct, further evidenced by his looking behind him to locate the defender prior to changing his line. If this isn’t obstruction then I don’t know what is!
there is an argument it was not material as the defender is unlikely to have caught up anyway, but in my view this was correctly disallowed.
