Yes it is a drinking issue, but usually people think it only affects soccer, when we know that these big rugby internationals in Cardiff are boozy parties which have so far escaped public scrutiny. So it's only fair to point the finger at rugby as well.
Stewards at soccer matches can and do refuse entry to heavily-drunk individuals. Do they do the same at the big rugby games? And there's no alcohol on the terraces.
Time for rugby to take a look at itself....
