All the players we have used can tackle, the problem is teamwork, which is crucial to our defence. Having a rookie at the back who may or may not be able to count, or talk, makes it harder. Having the backs constantly changed due to mid-game injuries doesn't help. Putting in rookies who haven't even been able to play lower grade doesn't help either.
So overall, a disaster!
But we aren't lacking in talent. I know all the players train for the same defence system, so I guess we either need to train harder at it. Or if our players are too dumb to get it right, maybe we need a simpler system.
