I've heard great things about the way his teams play. I'm sure for the truly elite player - He will be a great fit.
And this not just for coach AD- but for a lot of the coaches that people feel are "Elite" - There will be many players under these coaches that will play at the highest level of college and a few that will make a living as a pro player- As evidenced above by someone saying how many Stanford, National Team, etc players he has been involved with.
But how many players have quit the game at too young of an age because some bald guy with an accent pushes them too much, too early? (A lot of the blame here belongs on the parent for putting their kid in the wrong environment) It's not just in soccer that this happens (see the recent "gymnastics" issues) . I say "buyer beware"- And really know if your player has the physical and mental toughness to be that type of player. There is nothing wrong with playing for a coach that doesn't berate you and playing for a "local" team.
I come from the old school where high school sports were king. You had A-hole HS coaches in most sports. But these coaches weren't full time football, basketball, baseball., soccer coaches. They had some other main source of income. They coached because they knew the game and loved (maybe just "liked") the game. They weren't making high-5 to 6 figure salaries and moving across the country for a "better" job to coach middle school or HS aged athletes. They stuck close to home and were part of the community. They seemed to do it for the kids and not for trying to get themselves elevated to a higher level of status in the youth coaching ranks.
Most people on this board would recognize if someone said "Tad", "Ebert", "Platini", "Walid" or "Camargo" at a dinner party (even if your kid never played for them). Why do we give these guys celebrity status? How many of you know the name of your kids Math or English teacher?
