I just posted a thought on my main soccer forum. Ongoing bashing of Berhalter and the subs he has used. Wrote a fairly long dissection of why I think most of these options are faulty but wanted to share my bottom line here.
"You are simply guessing, sure maybe educated guessing, that had the changes suggested been made that they would have been better, the same, OR worse than what was actually done. Its easy to chastise things when there is no way to know what actually would have transpired."
Its easy to be an internet expert on something like this, and yes me included, when you can't be proven wrong.
