Sorry, but it IS the manager. It is all about leadership and work ethics. If Bradley get his son to play and he is allowed to go on doing so, then the US federation or whatever is called should fire him if they can't cope with it. Someone said it loud that when Mexico was under Sven it sucked. I agree, how can a NT team change so much just by a change in manager? Because it matters who is in charge, who he picks for the team, what system implements and how he chooses to do the work and address players in training and matches. I agree with you that systems matter more than a bit, but only in producing good players, not in producing results.
Ummm have any of you watched Bradley play? I don't like Bob at all but Michael is a solid CM. To say that he plays him just b/c he is his son just makes you all sound like idiots.
