They are in a unique position though.
Just suppose that a cashed up club or two isnt happy with their current Coach, and are interested in one of the best halves in the game as well as a TOP Coach
The halfback doesnt have to undersell himself in any way. He can still sell his services for top price.
They may intend to pay the Coach a mill per season (or whatever is the going rate at that time)
Thats where the uniqueness( if there is such a word), comes in.
lets say that one of the above mentioned clubs, is agreeable to pay the Half top price and so is another club, They cant go higher than the Cap allows. Officially
BUT, if one of the club is happy to pay extra money to the Coach, whose contract isnt covered by the Cap( i think thats still the situation) say half a mill.
Whose to know where that extra money would wind up. A good accountant would not have much trouble in muddying the waters.
It would be a big attraction to the Coach and player, and mostly, if not completely, it wouldnt be illegal,
it ALSO wouldnt present any problems for the Cap either
Maybe I've got it wrong, but I cant see why there would be a problem.
