Well known fact: every clubs has gaps. (not as well known: this is a short post. How lucky are you?)
Even if you have a great team, there’s ALWAYS something that can be improved upon. If you’re starting from scratch, you want to have your talent even distributed around the field. You don’t want to have a great midfield at the expense of your back line. You don’t want a great ruck men and no good kicks up front. Keep it even, folks, keep it even (in this case, the best defence is NOT a good offense).
A good starting point? Three great mid-fielders, 2 great forwards, 2 great defenders and 1 fabulous ruckmen.
