Hmm! Champion teams are anywhere, anytime, any conditions teams. Their form might vary a little according to conditions, but not to the extent of HRs in such a short time. And I'm confident Uncle Mick won't be using that as an excuse.
AM, if you are stating to everyone as per your initial comment that HR can't handle the wet or the cold, then that is an issue between you, Uncle Mick and others.
As for your last comment, I'd be interested to know how much experience you've had with premiership teams. I've seen tall, marking teams languish mid season then power to a flag. I've seen small, running teams get bogged down mid season but flourish when it counts. Some teams win all year and others create momentum. Which is better? It doesn't matter whether you handles the wet, or the wind or not - it never records the season's ups or downs next to a premiership.
Your original comment to HR? At best, I presume it was a poor attempt at humour between comrades. At worst, it was stupid.
