Right, so this was a roster shortfall that you, a deadshit nuffy, was aware of that Brad Arthur only just figured out?
How many backup hookers are there who are good enough to get on the field in one of the hardest, most important positions on the field? Are there enough for every club to have one? Do you think the clubs without one aren't aware they need one? Are they maybe struggling to get their top 17 right before worrying about getting the best backups at a reasonable price?
Just because there's a problem doesnt mean it can be fixed instantly. It certainly doesn't mean the people responsible for fixing it are unaware. They don't live in a perfect world where every problem can be solved simultaneously. Only sports fans and political pundits live in such a world.
