You'd think so, except a lot of what I'm seeing from Galaxy fans -- online, anyway -- seems to suggest that winning covered up a lot of issues for a long time.
It seems a lot of fans feel the FO is out of touch and content to coast on the team's past accomplishments as the once-premier team in MLS gets passed by the Atlanta Uniteds and TFCs of the world. Plus, their academy and development system is a wreck -- they've completely failed to develop any homegrown players that can actually contribute to the first team outside of Gyasi Zardes and there are few Galaxy academy kids in the national team set up. And it definitely doesn't help that LA is a horrible sports town.
That being said, I'd probably trade our problems for theirs.
Zardes was "developed" by the Galaxy in only the loosest terms possible. He joined their academy in 2008, was there just long enough to hit the HGP threshold, then went and played four years at Cal State-Bakersfield.
Like you said, their academy and development system is a wreck, and Zardes isn't really a counter to that argument.
