I'm done complaining about Greg's tactics. That horse is dead.
But a great team has to have the ability to say, "Whatever else happens, you're not scoring against us today. It might end 0-0, but you're not scoring."
The US still isn't close to being able to do that - even against mid-level competition.
And once you get past our front line of (mostly European) guys, we run out of options very quickly. MLS is still a ways away from producing the kind of depth in quality you need from a domestic league.
