Not really. If your best 9 isn't the best player in his club, and the better player plays for one of your major rivals, that's not ideal is it?
When taking about wallaby selection, wouldn't the best Aussie 9 at the club be th player your discussing?
If we were to compare Sarel to Mckibbon, there are pros and cons for each, it's nit clear cut.
The thread about if Mckibbon is up to wallaby duty, my opinion is he is not.
But in answe to your question of him not being the best 9 at the club, he is being consistently picked ahead Sarel and that doesn't look like changing. Soe say it os for his goal kicking, but even if that's the only reason, it's a reason Sarel diesnt bring to the table making McKibbon more valuable again.
